21    Cut, copy and paste operations are supported on columns (rectangular areas
22    of text), as well as on ordinary regions.
23</p>
24<p>
25    To mark a column, put the caret at one corner of the desired area and
26    control shift left click with the mouse at the opposite corner. If things
27    go well, the column will be highlighted appropriately.
28</p>
29<p>
30    Once a column is marked, the commands
31    <a href="commands.html#copyRegion">copyRegion</a>, mapped by default to
32    Ctrl C, <a href="commands.html#killRegion">killRegion</a>, mapped by
33    default to Ctrl X, and <a href="commands.html#delete">delete</a>, mapped
34    by default to Delete, act on the marked column.
35</p>
36<p>
37    The contents of the last column to be copied or killed are saved, and can
38    subsequently be retrieved with the command
39    <a href="commands.html#pasteColumn">pasteColumn</a>.
40</p>
41<p>
42    Copied or killed columns are not stored in the kill ring, so
43    <a href="commands.html#cyclePaste">cyclePaste</a> cannot be used with
44    columns.
