Commands



about

Displays the about box.

Default key mapping: None

alias

Sets or modifies an alias. See Aliases.

Default key mapping: None

alignStrings

Prompts for a regular expression and aligns the first occurrence of the specified regular expression in each line of the selected region.

For example, suppose you start with a region that looks like this:

        private static final int STATE_VARIABLE = STATE_LAST + 1;
        private static final int STATE_HERE_DOCUMENT = STATE_LAST + 2;
        private static final int STATE_POD = STATE_LAST + 3;
        private static final int STATE_REGEXP_DELIMITER = STATE_LAST + 4;
        private static final int STATE_REGEXP = STATE_LAST + 5;
        private static final int STATE_SUBST = STATE_LAST + 6;
If you specify "=" as the regular expression, alignStrings will reformat the region like this:
        private static final int STATE_VARIABLE         = STATE_LAST + 1;
        private static final int STATE_HERE_DOCUMENT    = STATE_LAST + 2;
        private static final int STATE_POD              = STATE_LAST + 3;
        private static final int STATE_REGEXP_DELIMITER = STATE_LAST + 4;
        private static final int STATE_REGEXP           = STATE_LAST + 5;
        private static final int STATE_SUBST            = STATE_LAST + 6;

Default key mapping: None

archiveOpenFile

Opens the file at the location of the caret or mouse click.

Default key mapping: Enter, Ctrl Shift G, Double Mouse-1, or Mouse-2 in Archive mode

attachFile

Attaches a file to the message in the current mail composition buffer.

Default key mapping: None

See also: Mail

backspace

If a region is marked, deletes it. Otherwise, deletes the character to the left of the caret.

Default key mapping: Backspace, Shift Backspace

binaryMode

Reloads the current buffer in binary mode.

Default key mapping: None

See also: defaultMode

bob

Moves to the beginning of the buffer.

Default key mapping: Ctrl Home

bounceMessage

Resends the current message to one or more specified addresses.

Default key mapping: 'b' in message buffers

See also: Mail

browseFileAtDot

Uses the default browser to view the file at the location of the caret.

For this command to work, you need to specify the properties browser and (optionally) browserOpts in your preferences file.

Default key mapping: Ctrl Shift B

ccGroup

This command is available in mail composition buffers when you're replying to a message. It adds all of the recipients of the original message to the "Cc:" header of your reply, just as if you had initiated the reply with messageReplyToGroup instead of messageReplyToSender.

Default key mapping: None

centerTag

Centers the current function vertically in the edit window.

Default key mapping: None

changes

Runs diff to display unsaved changes to the current buffer (if any). In the resulting output buffer, you can use diffGotoFile, mapped by default to Enter, to jump to the location of a particular change.

Because it uses diff, this command will not work unless diff is installed and in your path, which is more likely to be the case on Unix than Windows.

Default key mapping: None

checkPath

Examines all the lines in the current buffer that start with "#include" and reports which included files can't be found in your include path (or in the current directory, if the filename is enclosed in quotes rather than in angle brackets). This command also recursively checks all the included files that it can find, and reports which (if any) of the files included by those files can't be found.

Default key mapping: None

See also: includePath, listIncludes, iList

clearRegister

Prompts for a register name and erases the contents of the specified register.

Register names must be lower case letters (a-z). The contents of registers persist automatically from one j session to the next.

Default key mapping: None

See also: editRegister, insertRegister, listRegisters, saveToRegister

closeAll

Closes all open buffers, leaving a directory buffer looking at the current directory.

Default key mapping: None

See also: closeOthers

closeOthers

Closes all open buffers except the current one.

Default key mapping: None

closeParen

Inserts a closing parenthesis and briefly moves the caret to the matching opening parenthesis.

Default key mapping: ')' in Java mode

commentRegion

Comments out each line in the selected region, or the current line if no region is selected.

Default key mapping: F11

See also: uncommentRegion

compile

Compiles the source file in the current buffer. You will be prompted for the compile command. (On Windows, this command is only supported for Windows 2000 and Windows XP.)

Default key mapping:

See also: recompile, Compilation Buffers

compose

Opens a new mail composition buffer.

Default key mapping: 'c' in Mailbox mode

See also: Mail

copyAppend

Appends the selected region (or the current line if no region is selected) to last entry in the kill ring.

Default key mapping: Ctrl Shift C

See also: copyRegion, killAppend

copyLink

In web mode, copies to the kill ring (and to the system clipboard) the link at the location of the caret.

Default key mapping: None

copyPath

In directory buffers, copies to the kill ring (and to the system clipboard) the full pathname of the file on the line containing the caret.

Default key mapping: None

copyRegion

Copies the contents of the selected region (or the current line if no region is selected). For normal regions, the copied text is placed in the kill ring. If the selected region is a column, the text is saved but not placed in the kill ring; it can be retrieved with the command pasteColumn.

Default key mapping: Ctrl C

See also: copyAppend, killRegion, paste, Columns

copyXPath

In XML mode, copies to the kill ring (and to the system clipboard) the path of the element at the current location of the caret.

Default key mapping: None

cppFindMatch

If the caret is on a line that starts with #if, #else, #elif or #endif, finds the matching expression. Otherwise, finds the match of the brace, parenthesis or bracket at the location of the caret.

Default key mapping: Ctrl M in C++ mode

cvs

Executes an arbitrary CVS command. The CVS command, together with any required flags, must be supplied as an argument. The name of the file associated with the current buffer is automatically appended to the command line, unless the argument you supply begins with "-H". For example:

        cvs status -v

or:

        cvs -H admin

Default key mapping: None

See also: CVS Support

cvsAdd

Adds the file associated with the current buffer to CVS. The file is not actually placed in the CVS repository until you use cvsCommit to make the change permanent.

Default key mapping: None

See also: CVS Support

cvsCommit

Opens a checkin buffer in which you can compose a CVS checkin comment for the file associated with the current buffer.

When your comment is ready, you can use the command finish, mapped by default to Ctrl Enter in the checkin buffer, to complete the checkin operation.

The file associated with the current buffer must already have been registered with CVS using cvsAdd or the CVS "add" command.

Default key mapping: None

See also: CVS Support

cvsDiff

Opens a diff output buffer showing the changes between the checked-in version of the file associated with the current buffer and your local copy.

Default key mapping: None

See also: CVS Support

cvsDiffDir

Opens a diff output buffer showing the changes between the checked-in version and your local copy for all the files in the current directory and its subdirectories.

Default key mapping: None

See also: CVS Support

cvsLog

Runs the CVS "log" command on the file associated with the current buffer. The output is displayed in a transient output buffer.

Default key mapping: None

See also: CVS Support

cycleIndentSize

Cycles through the most plausible possibilities for the indent size of the current buffer (2, 4 and 8 spaces). The value that is currently in effect is shown in the status bar.

If you use cycleIndentSize to set the indent size, j will try to remember the setting the next time you open the same file.

Default key mapping: Alt I in most programming modes

cyclePaste

If the last command to be executed was not paste or cyclePaste, cyclePaste does exactly the same thing as paste.

If the last command to be executed was paste or cyclePaste, cyclePaste fetches the next item from the kill ring and inserts it in place of the text inserted by the last paste or cyclePaste.

What this means in practice is that you can invoke cyclePaste repeatedly to cycle through the contents of the kill ring, stopping when you see that the text you want has been inserted. If you can't find what you want and would like to cancel the operation, use undo.

Default key mapping: Ctrl Shift V

cycleTabWidth

Cycles through the most plausible possibilities for the tab width of the current buffer (2, 4 and 8 spaces). The value that is currently in effect is shown in the status bar.

This is intended to be a quick way to figure out the proper tab width to use when you've loaded a file for the first time and the indentation looks goofy. Just press Alt T repeatedly until things look right. Of course that may not happen; bear in mind that cycleTabWidth only considers the three most common possibilities.

If you use cycleTabWidth to set the tab width, j will try to remember the setting the next time you open the same file.

Default key mapping: Alt T

decodeRegion

Base 64 decodes the selected region (or the line containing the caret if no region is selected). If the resulting output is text, it is displayed in a new buffer; otherwise, you are prompted for a filename and the output is saved in the specified file.

Default key mapping: None

defaultMode

Reloads the current buffer in its default mode.

Default key mapping: Ctrl Alt B in binary mode

See also: binaryMode

delete

If a region is marked, deletes it. Otherwise, deletes the character at the location of the caret.

Default key mapping: Delete

detabRegion

Replaces tab characters in the selected region with the appropriate number of spaces, based on the tab width of the buffer. Buffer-specific settings such as tabWidth may be inspected and modified in the Properties dialog (see properties).

Default key mapping: None

See also: entabRegion

deleteWordLeft

Deletes the word to the left of the caret.

Default key mapping: Ctrl Backspace

See also: killWordLeft

deleteWordRight

Deletes the word to the right of the caret.

Default key mapping: Ctrl Delete

See also: killWordRight

describeKey

Displays information about the command mapped to a particular key or key combination.

Default key mapping: Alt K

diffGotoFile

Jumps to the location in the source buffer corresponding to the current line in the diff output buffer.

Default key mapping: Enter, Ctrl Shift G, Double Mouse-1, or Mouse-2 in Diff mode

See also: changes

dir

Opens a directory buffer on the current directory. The current directory is normally the parent directory of the file that is open in the current editor window.

Default key mapping: Ctrl D

See also: Directory Buffers.

dirBack

Changes to the previous directory in the history list for the current directory buffer.

Default key mapping: 'b' in directory buffers

See also: Directory Buffers.

dirBrowseFile

Uses the default browser to view the file at the location of the caret.

For this command to work, you need to specify the properties browser and (optionally) browserOpts in your preferences file.

Default key mapping: Ctrl Shift B in directory buffers

See also: Directory Buffers.

dirCopyFile

Copies the file at the current location of the caret to a specified destination. You can specify either a filename or a directory as the destination.

Default key mapping: Alt C in directory buffers

See also: Directory Buffers.

dirCycleSortBy

Cycles through the possibilities (name, date, size) for the sort order of the directory listing. The sort order that is currently in effect is displayed in the title bar of the editor window.

Default key mapping: S in directory buffers

See also: Directory Buffers.

dirDeleteFiles

Deletes the marked files, or, if no files are marked, deletes the file at the current location of the caret.

Default key mapping: Delete in directory buffers

See also: Directory Buffers.

dirDoShellCommand

Prompts for a shell command and executes the specified command on all the marked files in the current directory buffer.

If no files are marked, the command is executed on the file at the current location of the caret.

If the command string contains '*', the command runs once, with the list of marked files in place of the '*'. The order of the list is the order of appearance in the directory buffer.

If the command string does not contain '*', the command runs separately for each file, with the file name added at the end of the command string.

In all cases, the command is executed in the current directory (the directory displayed in the directory buffer).

Default key mapping: '!' in directory buffers

See also: Directory Buffers.

dirForward

Changes to the next directory in the history list for the current directory buffer.

Default key mapping: 'f' in directory buffers

See also: Directory Buffers.

dirGetFile

Copies the remote file at the current location of the caret to a specified destination on the local machine. You can specify either a filename or a directory as the destination.

Default key mapping: G in remote directory buffers

See also: Directory Buffers.

dirHome

If the caret is to the right of the first character of the filename on the current line, moves the caret to the first character of the filename. Otherwise, moves the caret to the beginning of the line.

Default key mapping: Home in directory buffers

See also: Directory Buffers.

dirHomeDir

If the current buffer is a directory buffer, changes to the home directory of the current user. Otherwise, finds an existing directory buffer or opens a new one on the home directory of the current user.

Default key mapping: None

See also: Directory Buffers.

dirMoveFile

Moves the file at the current location of the caret to a specified destination. You can specify either a filename or a directory as the destination.

Default key mapping: Alt M in directory buffers

See also: Directory Buffers.

dirOpenFile

Opens the file or directory at the location of the caret or mouse click.

Default key mapping: Enter, Ctrl Shift G, Double Mouse-1, or Mouse-2 in directory buffers

See also: Directory Buffers.

dirRescan

Refreshes the directory listing for the current directory buffer and rescans the directory tree.

Default key mapping: None

See also: Directory Buffers.

dirLimit

Sets a limit pattern (something like "*.java") to control what files are displayed in the directory listing. Entering a blank string removes the limit, so that all files are displayed.

Default key mapping: 'l' in directory buffers.

See also: dirUnlimit, Directory Buffers.

dirTagFile

Tags or untags the file at the current location of the caret.

Default key mapping: 't' in directory buffers

See also: Directory Buffers.

dirUnlimit

Removes any limit pattern that may be in effect for the current directory buffer, so that all files are displayed.

Default key mapping: 'L' in directory buffers.

See also: dirUnlimit, Directory Buffers.

dirUpDir

Navigates to the parent of the current directory.

Default key mapping: 'u' and Backspace in directory buffers

See also: Directory Buffers.

doShellCommandOnRegion

Prompts for a shell command and then executes that command, using the selected region as input. The contents of the selected region are replaced by the output of the command. If an error occurs, you can use undo to restore the previous contents.

doShellCommandOnRegion is an experimental command, not enabled by default. On Windows, you need to have the Cygwin tools installed, and sh.exe must be in your path.

Default key mapping: None

down

Moves the caret down one line.

Default key mapping: Down arrow

dropBookmark

Drops a numbered bookmark at the location of the caret in the current buffer. By default, dropBookmark is mapped to the ten keystrokes Alt 0 through Alt 9, and gotoBookmark is mapped by default to the ten keystrokes Ctrl 0 through Ctrl 9. When you drop a bookmark with Alt n, you can return to it with Ctrl n. It's possible to unmap these keystrokes or map other commands to them, but the current implementation of dropBookmark and gotoBookmark only works with these key mappings.

You can still return to a bookmark even if the buffer it refers to has been closed (in that case the buffer will be re-opened in the current frame), but bookmarks are not retained from one session to the next.

Default key mapping: Alt 0 through Alt 9 (bookmarks 0-9)

See also: gotoBookmark

editRegister

Prompts for a register name and opens a buffer so you can edit the contents of the specified register.

Register names must be lower case letters (a-z). The contents of registers persist automatically from one j session to the next.

Default key mapping: None

See also: clearRegister, insertRegister, listRegisters, saveToRegister

electricCloseAngleBracket

Inserts '>' and, if the property autoIndent is true, re-indents the current line according to context.

Default key mapping: '>' in HTML and XML modes

electricCloseBrace

Inserts '}' and re-indents the current line according to context. If the property autoNewline is true, also inserts a line separator and moves the caret to the appropriate column on the new line.

Default key mapping: '}' in Java, JavaScript, C and C++ modes

See also: electricOpenBrace

electricColon

Inserts a colon at the current location of the caret and re-indents the current line according to context. If the property autoNewline is true, also inserts a line separator and moves the caret to the appropriate column on the new line.

Default key mapping: ':' in Java mode

electricOpenBrace

Inserts '{' and re-indents the current line according to context. If the property autoNewline is true, also inserts a line separator and moves the caret to the appropriate column on the new line.

Default key mapping: '{' in Java, JavaScript, C and C++ modes

See also: electricCloseBrace

electricPound

Inserts a '#' character at the current location of the caret. If the line contains only whitespace, the '#' will be forced into the first column.

Default key mapping: '#' in C and C++ modes

electricSemi

Inserts a semicolon at the current location of the caret and re-indents the current line according to context. If the property autoNewline is true, also inserts a line separator and moves the caret to the appropriate column on the new line.

Default key mapping: ';' in Java, JavaScript, C and C++ modes

electricStar

Inserts '*' at the current location of the caret and, if the current line is otherwise blank, re-indents the line according to context.

Default key mapping: '*' in Java, JavaScript, C and C++ modes

end

Moves the caret to the end of the current line.

If the preference extendEnd is true, invoking end repeatedly in quick sequence triggers special behavior after the caret reaches the end of the current line: the caret is first moved to the bottom of the edit window, and then to the end of the buffer. There is a one-second timeout on this operation, meaning that if one second elapses between invocations of end, the second invocation is viewed as an independent event rather than a repetition of the first, and the special behavior is not triggered.

Default key mapping: End

See also: home

entabRegion

Replaces spaces with tab characters in the selected region, based on the tab width of the buffer. Buffer-specific settings such as tabWidth may be inspected and modified in the Properties dialog (see properties).

Default key mapping: None

See also: detabRegion

eob

Moves the caret to the end of the buffer.

Default key mapping: Ctrl End

eol

Moves the caret to the end of the line.

Default key mapping: None

evalBuffer

Executes the BeanShell script in the current buffer.

Default key mapping: None

escape

Escapes from the last operation.

More specifically, closes the most recently visited transient buffer (and possibly unsplits the window). Transient buffers include help buffers, list occurrencess buffers, and compilation buffers.

If no transient buffer is currently displayed, clears the selection (if any) in the current buffer.

Otherwise, cancels any background process associated with the current buffer.

Each invocation of escape does at most one thing.

Default key mapping: Escape

executeCommand

Executes an editor command by name. The "Command:" textfield in the location bar supports both history (using the up and down arrow keys) and completion (using Tab and Shift Tab).

Some commands (for example, insertString, help, jdkHelp, and source) require or accept an argument (which in the current implementation is always a string). Such commands can be entered like this:

        insertString this is a test
or like this:
        insertString("this is a test")
Default key mapping: Alt x

expand

Replaces the text to the left of the caret with a word in the current buffer for which that text is a prefix.

The expand command takes the sequence of characters you've just typed (more precisely, the sequence of characters that are legal in a Java identifier, beginning immediately to the left of the caret), looks through the entire buffer for words (i.e. legal Java identifiers) that have the sequence in question as a prefix, and replaces the sequence of characters with the first match it finds.

If you don't like that particular replacement, you can hit Alt Space (or Alt /) again (and again and again) to cycle through all the possible replacements. If you don't like any of the replacements, you can use undo, mapped by default to Ctrl Z, or escape, mapped by default to Escape, at any point, and get back where you started.

In the header area of a mail composition buffer, expand looks for completions in the global address book, rather than in the text of the buffer, so you can use it to auto-complete mail addresses.

This functionality is also available in all of j's textfields (both in dialog boxes and in the location bar), with the same default key mappings. In a textfield, the expansion text is taken from the current buffer, and the expansion can be cancelled by pressing Escape.

Default key mapping: Alt Space and Alt /

find

Prompts for a pattern and finds the next occurrence of the specified pattern in the current buffer.

The search is case-insensitive if the "Ignore case" checkbox is checked.

If the "Whole words only" checkbox is checked, a match is returned only if it is both preceded and followed by a non-word character (i.e. a character not legal in an identifier, based on the mode of the buffer).

If the "Regular expression" checkbox is checked, the pattern is interpreted as a regular expression rather than as a simple string.

If the "Multiline pattern" checkbox is checked, the regular expression can contain newline characters ("\n"). Because of the way j handles things internally, a single "\n" should be used to match a newline even if the file being edited uses "\r\n" or "\r" as its line separator string. (The "Multiline pattern" feature is experimental and is not enabled by default.)

If the "List occurrences" checkbox is checked, all lines in the current buffer that match the specified pattern are listed.

If the "Search from start of document" checkbox is checked, the search begins at the start of the document. Otherwise, the search begins at the current location of the caret.

Default key mapping: Ctrl F or Alt F3

Note: If you set useIncrementalFind to true in your preferences file, incrementalFind will be mapped by default to Ctrl F.

findFirstOccurrence

Finds the first occurrence in the current buffer of the word at the current location of the caret.

The search is case-sensitive and is carried out as if the "whole words only" option was specified.

Default key mapping: Ctrl Alt Up

See also: findNextWord, findPrevWord

findInFiles

Prompts for a pattern and a file specification and generates a list of all occurrences of the specified pattern in files matching the file specification.

Several file specifications can be supplied at once, separated by semicolons. If the full path is not given in a file specification, the current directory or the directory last specified by a full path is used.

For example, if the file specification is *.c;/usr/src/emacs-20.3/src/*.c;*.h, the search will examine .c files in the current directory and .c and .h files in /usr/src/emacs-20.3/src.

The search is case-insensitive if the "Ignore case" checkbox is checked.

If the "Whole words only" checkbox is checked, a match will only be returned if it is both preceded and followed by a non-word character (i.e. a character not legal in a Java identifier).

If the "Regular expression" checkbox is checked, the pattern will be interpreted as a regular expression rather than a simple string.

If the "Include subdirectories" checkbox is checked, the search will recurse into any subdirectories of directories in the file specification. For example, if the file specification is /usr/src/linux/*.c, the search will examine .c files in /usr/src/linux and all of its subdirectories.

If the "Search files in memory" checkbox is checked, if a file matching the file specification is currently loaded in a buffer, the contents of the buffer will be searched rather than the file as last saved on disk, so unsaved changes to the buffer will be taken into account.

You can use the command escape, mapped by default to Escape, to cancel a search in progress.

Default key mapping: Ctrl Shift F, F6

See also: listFiles

findMatchingChar

Finds the match of the brace, parenthesis or bracket at the location of the caret.

Default key mapping: Ctrl M

findNext

Finds the next match in the current search (initiated by find, incrementalFind, findNextWord or findPrevWord).

Default key mapping: F3, Ctrl G

findNextWord

Finds the next occurrence in the current buffer of the word at the current location of the caret.

The search is case-sensitive and is carried out as if the "whole words only" option was specified.

Default key mapping: Alt Down

See also: findFirstOccurrence, findPrevWord

findOccurrenceAtDot

Jumps to the line in the source file corresponding to the current line in a List Occurrences buffer.

Default key mapping: Enter or Ctrl Shift G in List Occurrences buffers

See also: mouseFindOccurrence

findPrev

Finds the previous match in the current search (initiated by find, incrementalFind, findNextWord or findPrevWord).

Default key mapping: Shift F3, Ctrl H

findPrevWord

Finds the previous occurrence in the current buffer of the word at the current location of the caret.

The search is case-sensitive and is carried out as if the "whole words only" option was specified.

Default key mapping: Alt Up

See also: findFirstOccurrence, findNextWord

findTag

Prompts for a tag (generally speaking, a tag is a function name) and moves the caret to the definition of the specified function. The current location of the caret is first saved on the marker stack as a temporary bookmark, so you can use popPosition, mapped by default to Shift F5, to get back where you came from.

Default key mapping: Ctrl T

See also: findTagAtDot, findTagAtDotOtherWindow, mouseFindTag

findTagAtDot

Jumps to the definition of the function at the current location of the caret. The current location of the caret is first saved on the marker stack as a temporary bookmark, so you can use popPosition, mapped by default to Shift F5, to get back where you came from.

Default key mapping: Alt . (Alt dot) in Java, C, C++, Lisp, Scheme and Perl modes

See also: findTag, findTagAtDotOtherWindow, mouseFindTag

findTagAtDotOtherWindow

Jumps to the definition of the function at the current location of the caret, using the other window (splitting the current window if necessary). Keyboard focus stays in the original window.

Default key mapping: Ctrl Alt . (Ctrl Alt dot) in Java mode and its derivatives

See also: findTag, findTagAtDot, mouseFindTag

finish

Completes the CVS checkin operation, using the contents of the current buffer as the checkin comment. This command is only available in CVS checkin buffers.

Default key mapping: Ctrl Enter in CVS checkin buffers

See also: CVS Support

fold

Creates a fold at (or near) the current location of the caret.

Default key mapping: Ctrl [ in Java, C, C++ and Perl modes

See also: foldMethods, unfold, unfoldAll

foldMethods

Folds all the methods in the current buffer.

Default key mapping: None

See also: fold, foldRegion, unfold, unfoldAll

foldRegion

Folds the marked region. The region in question must consist of full lines; in other words, both dot and mark must be in column 1.

Default key mapping: None

See also: fold, foldMethods, unfold, unfoldAll

gotoBookmark

Returns to a previously dropped numbered bookmark. By default, dropBookmark is mapped to the ten keystrokes Alt 0 through Alt 9, and gotoBookmark is mapped by default to the ten keystrokes Ctrl 0 through Ctrl 9. When you drop a bookmark with Alt n, you can return to it with Ctrl n. It's possible to unmap these keystrokes or map other commands to them, but the current implementation of dropBookmark and gotoBookmark only works with these key mappings.

You can still return to a bookmark even if the buffer it refers to has been closed (in that case the buffer will be re-opened in the current frame), but bookmarks are not retained from one session to the next.

Default key mapping: Ctrl 0 through Ctrl 9 (bookmarks 0-9)

See also: dropBookmark

gotoFile

Opens the file at the location of the caret or mouse click.

Default key mapping: Ctrl Shift G (global), Mouse-2 (shell buffers)

help

Displays help.

For this command to work, you may need to set the docPath property in your preferences file to point to the directory containing the documentation:

        docPath=/home/peter/j/doc
For Windows, you'll need to use double backslashes, like this:
        docPath=c:\\j\\doc
If you use executeCommand to invoke help, you can specify the command you want help on at the same time:
        help executeCommand
or
        help("executeCommand")
Default key mapping: F1

See also: executeCommand

home

Moves the caret to the beginning of the text on the current line, if the caret is to the right of that location to begin with. If the caret is already at the beginning of the text on the current line or in the whitespace to the left of the text, home moves the caret to column 1 on the same line.

If the preference extendHome is true, invoking home repeatedly in quick sequence triggers special behavior after the caret reaches column 1 on the current line: the caret is then moved to the top left corner of the edit window, and then to the beginning of the buffer. There is a one-second timeout on this operation, meaning that if one second elapses between invocations of home, the second invocation is viewed as an independent event rather than a repetition of the first, and the special behavior is not triggered.

extendHome is false by default.

Default key mapping: Home

See also: end

htmlBold

Inserts an HTML bold tag ("<B>") before the selected text (or before the location of the caret, if there's no selection) and an HTML end tag ("</B>") after the selected text (or after the location of the caret).

The case of the inserted tags is controlled by the property HtmlMode.upperCaseTagNames, which is true by default.

Default key mapping: Ctrl B in HTML mode

See also: htmlInsertTag

htmlElectricEquals

Inserts '=' at the current location of the caret.

In HTML mode, if the property HtmlMode.attributesRequireQuotes is true, and if the '=' immediately follows an attribute name, and if the character following the '=' is either whitespace or '>', this command inserts a pair of double quotation marks after the '=' and positions the caret between the quotation marks.

The effect of this is to make it possible to enclose attribute values in quotation marks without having to type the quotation marks themselves.

Default key mapping: '=' in HTML mode

See also: xmlElectricEquals

htmlEndTag

Inserts an empty HTML end tag, with the caret positioned after the opening "</".

Default key mapping: Ctrl Shift .

htmlFindMatch

Finds the match to the HTML tag at the location of the caret. Nested tags are handled correctly.

Default key mapping: Ctrl M in HTML mode

htmlInsertMatchingEndTag

Inserts the HTML end tag corresponding to the last HTML start tag before the location of the caret. Nested tags are not currently supported.

Default key mapping: Ctrl E in HTML mode

htmlInsertTag

Inserts an HTML start tag and (if appropriate) the corresponding end tag, enclosing the current selection. If no selection is marked, the start and end tags will enclose the word at the current location of the caret, if any.

If the property HtmlMode.fixCase is true, the tag name will be converted to the preferred case (as specified by HtmlMode.upperCaseTagNames when it is inserted in the buffer.

J will normally insert an end tag unless it is forbidden. You can customize this behavior by supply a tag customization file; see HtmlMode.tags.

Default key mapping: Ctrl Shift , (Ctrl Shift comma) in HTML mode

or for IMAP:
        inbox = {peter@annie}inbox
Default key mapping: None

See also: openMailbox, Mail

incrementalFind

Prompts for input and finds the string entered, as it is typed in.

The search is case-insensitive unless (or until) the pattern contains at least one upper case character.

In the incremental find textfield, any key combination mapped to incrementalFind or findNext can be used to search for the next occurrence of the current pattern, and any key combination mapped to findPrev can be used to search for the previous occurrence of the pattern. (By default, findNext is mapped to F3 and Ctrl G, and findPrev is mapped to Shift F3 and Ctrl H.)

Ctrl W can be used to copy text from the buffer into the search pattern. Ctrl W copies the text from the buffer starting at the current location of the caret up until the end of the current word (or the end of the next word, if the caret is already at the end of the current word).

Ctrl P and Ctrl N can be used to navigate through the history list of previously used search patterns.

If you invoke incrementalFind and then realize you'd rather use find instead, you can get there by simply pressing Enter (as long as the incremental find textfield is empty).

Default key mapping: None

Note: If you set useIncrementalFind to true in your preferences file, incrementalFind will be mapped by default to Ctrl F.

indentLine

Applies j's idea of correct indentation to the current line.

Default key mapping: Ctrl Shift [ in Java, JavaScript, C and C++ modes

insertByte

Inserts the character that corresponds to the specified byte in the default encoding at the current location of the caret. The byte must be specified as a decimal, hexadecimal or octal number. A leading zero denotes an octal number; a leading "0x" or "0X" denotes a hexidecimal number; otherwise the number is assumed to be decimal.

Default key mapping: None

insertChar

Inserts the specified Unicode character at the current location of the caret. The character must be specified as a decimal, hexidecimal or octal number. A leading zero denotes an octal number; a leading "0x" or "0X" denotes a hexidecimal number; otherwise the number is assumed to be decimal.

Default key mapping: None

insertKeyText

Inserts the next key combination you type (which can be a single key like Enter or Backspace, or a combination like Ctrl Alt S) as a string (like "Enter" or "Backspace" or "Ctrl Alt S") at the location of the caret in the current buffer. The action mapped to the key combination in question (if any) is not performed. Useful for editing a custom key map. The inserted text is guaranteed (well, not guaranteed, exactly, but extremely likely) to be in a format recognizable by j's key map parser.

Default key mapping: None

insertParentheses

If a region is selected, inserts parentheses around the selected region. Otherwise, inserts an opening parenthesis followed by a closing parenthesis, leaving the caret positioned between them.

If parensRequireSpaces is true, single space characters are added after the opening parenthesis and before the closing parenthesis.

Default key mapping: Ctrl Shift ( in Java, JavaScript, C, C++, and Perl modes

See also: movePastCloseAndReindent

insertRegister

Prompts for a register name and inserts the contents of the selected register at the location of the caret in the current buffer.

Default key mapping: None

Abbreviation: ir

See also: clearRegister, editRegister, listRegisters. saveToRegister

insertString

Requires a string argument. The supplied string argument is inserted in the current buffer at the location of the caret. Can be invoked using executeCommand or mapped to a key combination in a global or mode-specific key map.

For example:

        insertString("e.printStackTrace( );")
Default key mapping: None

See also: executeCommand

insertTab

If useTabs is true for the current buffer, inserts a tab character at the location of the caret, otherwise inserts the appropriate number of spaces, based on the buffer's indentSize. Buffer-specific settings such as useTabs and indentSize may be inspected and modified in the Properties dialog (see properties).

Default key mapping: Ctrl Tab in Java and HTML modes

jdkHelp

Displays the JDK HTML help file corresponding to the class name at the location of the caret or mouse click.

The help file is displayed in another window, splitting the current window if necessary. The help buffer can subsequently be dismissed using escape, mapped by default to Escape.

For this to work, you need to add a line to your preferences file specifying the location of the JDK documentation:

        jdkDocPath=/home/peter/sun/jdk1.3/docs

Default key mapping: Alt F1 in Java mode

See also: jdkDocPath

jmips

Measures the performance of the underlying Java runtime system (which is, of course, dependent on the performance of the underlying hardware). The result is displayed in the status bar.

Default key mapping: None

jumpToColumn

Prompts for a column number and moves the caret to the specified column.

The column number can be a simple number ("123"), an arithmetic expression ("100+23"), or a positive or negative offset from the current location ("+7", "-12").

Default key mapping: None

jumpToLine

Prompts for a line number and moves the caret to the beginning of the specified line.

The line number can be a simple number ("123"), an arithmetic expression ("100+23"), or a positive or negative offset from the current location ("+7", "-12").

Default key mapping: Ctrl J

jumpToOffset

Prompts for an absolute offset (the number of characters from the start of the buffer) and moves the caret to the specified location.

The offset can be a simple number ("123"), an arithmetic expression ("100+23"), or a positive or negative offset from the current location ("+7", "-12").

Default key mapping: None

See also: offset

Default key mapping: Ctrl Shift W

killLine

Copies the text from the location of the caret to the end of the current line to the kill ring and then deletes that text. If the text to be deleted is nothing but whitespace, or if the caret is already at the end of the line, the following line separator is copied to the kill ring and deleted too.

Default key mapping: Ctrl K

killRegion

Deletes the selected region (or the current line if no region is selected). For normal regions, the deleted text is placed in the kill ring. If the selected region is a column, the deleted text is saved but not placed in the kill ring; it can be retrieved with the command pasteColumn.

Default key mapping: Ctrl X

See also: copyRegion, Columns

killWordLeft

Default key mapping: Alt L

listOccurrencesOfPatternAtDot

Lists all occurrences in the current buffer of the selected text (if any) or of the word at the current location of the caret.

If text is selected on the current line, the selected text is used as the pattern for the search, and the search is carried out as if the "whole words only" option was not specified.

If there is no selection on the current line, the word at the current location of the caret is used as the pattern, and the search is carried out as if the "whole words only" option was specified.

The search is case-sensitive (in both cases).

Multi-line selections are not supported.

Default key mapping: Ctrl Alt L

mousePaste

If a selection is marked, the contents of the selected region are copied to the kill ring, and the region is deselected. Then the copied text is inserted at the location of the mouse click.

If no selection is marked, mousePaste is equivalent to paste at the location of the mouse click.

If the text to be inserted ends with a line separator, it is inserted above the line where the mouse click occurred, as if the mouse click were in the first column of the line, even if that is not the case. The intention behind this is to make it easy to paste whole lines of text (or blocks of lines), without having to click exactly at the beginning of the line. If possible, the indentation of the inserted lines is corrected to match their new context.

Default key mapping: None

See also: paste, cyclePaste, pasteColumn

openFile

Sets focus to the edit control in the location bar of the current window, where you can enter a filename and press Enter to activate the corresponding buffer, if it exists, or else create and activate a new buffer for the specified file.

If the specified file is not found in the current directory, j will look for it first in the include path (if it's a .h file) and then in the source path. You can define include and source paths in your preferences file. If j can't find the file you specify, you will be asked if you want to create it.

The edit control supports both history (using the up and down arrow keys) and completion (using Tab and Shift Tab).

In addition to normal text files, you can open a directory, a .zip or .gz file, or a URL (like http://armedbear.org).

If you press Enter with no text in the edit control, you will get a directory buffer on the current directory.

Default key mapping: Ctrl O

See also: Directory Buffers.

openFileInOtherFrame

Same as openFile, but the specified file is opened in a different (possibly new) frame (top-level editor window). You will be prompted to enter the filename in a dialog box, rather than in the location bar of the current window.

Default key mapping: Page Up

paste

The contents of the system clipboard (if any) are appended to the kill ring, and then the last item from the kill ring (which will be the contents of the system clipboard, if anything was there) is inserted at the current location of the caret.

If a block is marked, the inserted text replaces the marked block.

If the text to be inserted ends with a line separator, it is inserted above the line containing the caret, as if the caret were in the first column of the line, even if that is not the case. The intention behind this is to make it easy to cut and paste whole lines of text (or blocks of lines), without having to move the caret to the beginning of the line. If possible, the indentation of the inserted lines is corrected to match their new context.

Default key mapping: Ctrl V

See also: cyclePaste, pasteColumn, mousePaste

pasteColumn

Inserts the last killed or copied column at the current location of the caret.

Default key mapping: None

See also: copyRegion, killRegion, paste, Columns

Default key mapping: F7

See also: playbackMacro

redo

Undoes the last undo.

Default key mapping: Ctrl Y

See also: undo

replace

Replaces one or more occurrences of one pattern with another.

If the "Ignore case" checkbox is checked, j tries, paradoxically, to preserve case, if possible, when it makes a replacement. More precisely, if the pattern is all upper case, j will make the replacement all upper case, and if the pattern begins with an upper case letter, j will make the replacement begin with an upper case letter. For example, if the pattern is "javaFormatter" and the replacement is "cppFormatter", "JAVAFORMATTER" will become "CPPFORMATTER", and "JavaFormatter" will become "CppFormatter". These are the only two situations in which the replacement string is altered to preserve case. Upper-case letters in the replacement string are NEVER converted to lower case. This may seem strange, but in practice, chances are good that this is the behavior you want.

If the "Whole words only" checkbox is checked, occurrences of the pattern will be replaced only if they are delimited by characters that cannot appear in a Java identifier. Generally speaking, Java identifiers can contain letters, digits, and the characters '$' and '_'.

If the "Regular expressions" checkbox is checked, the pattern will be interpreted as a regular expression rather than as a literal string. In addition, the replacement string can refer to all or part of what is matched by the pattern. "\&" in the replacement string will be replaced with the entire string that matched the pattern. "\n", where n is a digit from 1 to 9, will be replaced by whatever matched the nth parenthesized grouping in the pattern. See Regular Expressions.

For example, if you specify this pattern:

    foo\((.*), (.*)\)
and this replacement:
    foo(\2, \1)
the effect would be to reverse the order of the arguments in every call to the function foo. Note that you need to escape the literal parentheses in the pattern, but not in the replacement.

If the "Multiline pattern" checkbox is checked, both the regular expression and the replacement can contain newline characters ("\n"). Because of the way j handles things internally, a single "\n" should be used to match a newline even if the file being edited uses "\r\n" or "\r" as its line separator string. (The "Multiline pattern" feature is experimental and is not enabled by default.)

If the "Restrict changes to selected text" checkbox is checked, only those occurrences of the pattern that fall within the current selection are replaced. Otherwise, if a block is marked, replacements are carried out starting at the beginning of the marked block.

If the "Confirm changes" checkbox is checked, you will be prompted to confirm each replacement.

Default key mapping: Ctrl R

replaceInFiles

Replaces one or more occurrences of one pattern with another in multiple files. If a file matching the file specification is already loaded in a buffer, the operation is performed on the contents of the buffer rather than the file as last saved on disk, so unsaved changes to the buffer are never lost. Files that were not previously loaded are saved automatically if any replacements are made. Buffers created specifically for the replace in files operation are deleted when they are no longer needed.

Several file specifications can be supplied at once, separated by semicolons. If the full path is not given in a file specification, the current directory or the directory last specified by a full path is used.

For example, if the file specification is *.c;/usr/src/emacs-20.3/src/*.c;*.h, the search will examine .c files in the current directory and .c and .h files in /usr/src/emacs-20.3/src.

If the "Ignore case" checkbox is checked, j tries, paradoxically, to preserve case, if possible, when it makes a replacement. More precisely, if the pattern is all upper case, j will make the replacement all upper case, and if the pattern begins with an upper case letter, j will make the replacement begin with an upper case letter. For example, if the pattern is "javaFormatter" and the replacement is "cppFormatter", "JAVAFORMATTER" will become "CPPFORMATTER", and "JavaFormatter" will become "CppFormatter". These are the only two situations in which the replacement string is altered to preserve case. Upper-case letters in the replacement string are NEVER converted to lower case. This may seem strange, but in practice, chances are good that this is the behavior you want.

If the "Whole words only" checkbox is checked, occurrences of the pattern will be replaced only if they are delimited by characters that cannot appear in a Java identifier. Generally speaking, Java identifiers can contain letters, digits, and the characters '$' and '_'.

If the "Regular expressions" checkbox is checked, the pattern is interpreted as a regular expression rather than as a literal string. In addition, the replacement string can refer to all or part of what is matched by the pattern. "\&" in the replacement string will be replaced with the entire string that matched the pattern. "\n", where n is a digit from 1 to 9, will be replaced by whatever matched the nth parenthesized grouping in the pattern. See Regular Expressions.

For example, if you specify this pattern:

        foo\((.*), (.*)\)
and this replacement:
        foo(\2, \1)
the effect is to reverse the order of the arguments in every call to the function foo. Note that you need to escape the literal parentheses in the pattern, but not in the replacement string.

If the "Confirm changes" checkbox is checked, you will be prompted to confirm each replacement.

Java recognizes both canonical names and aliases for a variety of encodings, and to make things more interesting, there are significant variations in this area among the different versions of Java. More information from the perspective of Java 1.4 is available here:

        http://java.sun.com/j2se/1.4/docs/guide/intl/encoding.doc.html

source

Finds the source of the Java class at the current location of the caret.

You can also use executeCommand and specify the name of the class along with the command:

        source javax.swing.JFrame
If the class is properly imported in the current buffer, the simple name is enough:
        source JFrame

For this command to work properly, you need to specify the location of the JDK source on your system by adding a line like this to your preferences file:

        jdkSourcePath = /home/peter/sun/j2sdk1.4.0/src
Default key mapping: Ctrl F1 in Java mode

See also: jdkSourcePath

splitWindow

Splits the current window horizontally. Only one split per frame is currently supported.

Default key mapping: F10

stamp

Inserts the current date and time at the location of the caret.

The format of the inserted string is controlled by the stampFormat property.

Default key mapping: Shift F2

tab

If a multi-line region is selected, or if the property tabAlwaysIndent is true, this command simply calls indentLineOrRegion.

Otherwise (i.e. no multi-line selection, tabAlwaysIndent is false), the behavior depends on the location of the caret.

If the caret is at the very beginning of the text on the line, or in the whitespace to the left of the text, tab calls indentLine. If the caret is in the midst of the actual text on the line, tab inserts either a single tab character or the equivalent number of spaces, depending on the setting of the useTabs property.

Default key mapping: Tab (in programming modes)

See also: insertTab

visibleTabs

Toggles the visibility of tab characters in the buffer. By default, tabs are not visible, and are displayed using the appropriate number of space characters, as you would expect. When you turn on visible tabs, tab characters are indicated by the character '^'.

Default key mapping: Ctrl Alt T

whatChar

Displays decimal, hex and character equivalents for the character at the current location of the caret.

Default key mapping: None

whereIs

Displays information about the keys mapped to a particular command.

Default key mapping: None

windowDown

Moves the window down one line (so that the text seems to move up one line), without changing the location of the caret.

Default key mapping: Ctrl Down

windowUp

Moves the window up one line (so that the text seems to move down one line), without changing the location of the caret.

Default key mapping: Ctrl Up

wordLeft

Moves the caret to the beginning of the current word, or, if the caret is already at the beginning of the current word, to the beginning of the previous word.

Default key mapping: Ctrl Left

wordRight

Moves the caret to the beginning of the next word.

Default key mapping: Ctrl Right

wrapComment

Wraps all the lines in the current multi-line comment at the wrap column, which by default is column 80. The wrap column is controlled by the property wrapCol, which is a buffer-specific setting that may be inspected and modified in the Properties dialog (see properties). You can set global and mode-specific defaults for wrapCol in your preferences file.

Default key mapping: F12 in Java, C, C++ and Perl modes

See also: wrapParagraph, wrapRegion

wrapParagraph

Wraps all the lines in the current paragraph at the wrap column, which by default is column 80. The wrap column is controlled by the property wrapCol, which is a buffer-specific setting that may be inspected and modified in the Properties dialog (see properties). You can set global and mode-specific defaults for wrapCol in your preferences file.

A paragraph is basically defined as a block of contiguous lines with blank lines before and after it. To make the definition a bit more flexible, a line starting with <p>, <br> or <pre> is recognized as the first line of a paragraph, even if the line before it is not blank. Similarly, a line ending with <p>, </p>, <br> or </pre> is recognized as the last line of a paragraph, even if the line after it is not blank.

This function does not move the caret, so you can reformat the paragraph and immediately continue typing right where you left off.

Default key mapping: F12

See also: unwrapParagraph, wrapComment, wrapRegion

wrapRegion

Wraps all the lines in the selected region at the wrap column, which by default is column 80. The wrap column is controlled by the property wrapCol, which is a buffer-specific setting that may be inspected and modified in the Properties dialog (see properties). You can set global and mode-specific defaults for wrapCol in your preferences file.

Default key mapping: None

See also: wrapComment, wrapParagraph

writeGlobalKeyMap

Prompts for a filename and writes out the current global key map to the specifed file, in human-readable form.

Default key mapping: None

writeLocalKeyMap

Prompts for a filename and writes out the local key map for the current buffer to the specifed file, in human-readable form. The local key map supplements (and possible overrides) global key assignments, based on the mode (Java, HTML, etc.) of the buffer.

Default key mapping: None

xmlElectricEquals

Inserts '=' at the current location of the caret.

In XML mode, if the '=' immediately follows an attribute name, and if the character following the '=' is either whitespace or '>', this command inserts a pair of double quotation marks after the '=' and positions the caret between the quotation marks.

The effect of this is to make it possible to enclose attribute values in quotation marks without having to type the quotation marks themselves.

Default key mapping: '=' in XML mode

See also: htmlElectricEquals

xmlElectricSlash

Inserts '/' at the current location of the caret.

In XML mode, if the '/' immediately follows '<', and if there is an unmatched start tag before the current location of the caret, the corresponding end tag is automatically inserted. The line is then automatically re-indented if autoIndent is true for the current buffer.

Default key mapping: '/' in XML mode

xmlFindCurrentNode

In XML mode, if XML parser support is available and the document tree is displayed in the sidebar, forces the tree to expand all the way down to the node corresponding to the location of the caret in the edit buffer.

Default key mapping: Ctrl = in XML mode

See also: XML Mode

xmlFindMatch

Finds the match to the XML tag at the location of the caret. Nested tags are handled correctly.

Default key mapping: Ctrl M in XML mode

xmlInsertEmptyElementTag

Inserts an XML empty element tag.

If the property XmlMode.fixCase is true, the tag name is converted to the preferred case (as specified by XmlMode.upperCaseTagNames) when it is inserted in the buffer.

Default key mapping: Ctrl Shift . (Ctrl Shift period) in XML mode

xmlInsertMatchingEndTag

If there is an unmatched start tag before the current location of the caret, automatically inserts the corresponding end tag.

Default key mapping: Ctrl E in XML mode

xmlInsertTag

Inserts an XML start tag and the corresponding end tag, enclosing the current selection. If no selection is marked, the start and end tags enclose the word at the current location of the caret, if any.

If the property XmlMode.fixCase is true, the tag name is converted to the preferred case (as specified by XmlMode.upperCaseTagNames) when it is inserted in the buffer.

Default key mapping: Ctrl Shift , (Ctrl Shift comma) in XML mode

xmlParseBuffer

In XML mode, parses the current buffer. If the operation succeeds, the document tree in the sidebar is updated. If an error occurs, the parser's error message is displayed in a message box and the caret is moved to the location of the error in the edit buffer.

Default key mapping: Ctrl P in XML mode
