further manipulation. Range selections are equivalent to selections in
most other text editors; they cover text between two points in a buffer.
In addition to the standard text-selection mode, jEdit also allows
<span class="bold"><strong>rectangular selections</strong></span> that cover a
rectangular area (some text editors refer to these as <span class="quote">“<span class="quote">column
selections</span>”</span>). Furthermore, several chunks of text can be selected
and operated on simultaneously.</p><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="d0e2482"></a>Range Selection</h3></div></div></div><p>Dragging the mouse creates a range selection from where the
mouse was pressed to where it was released. Holding down
<code class="keycap">Shift</code> while clicking a location in the buffer will
create a selection from the caret position to the clicked
location.</p><p>Holding down <code class="keycap">Shift</code> in addition to a caret
movement key (<code class="keycap">LEFT</code>, <code class="keycap">UP</code>,
<code class="keycap">HOME</code>, etc) will extend a selection in the specified
direction.</p><p><span class="guimenu"><strong>Edit</strong></span>><span class="guimenuitem"><strong>Select
All</strong></span> (shortcut: <code class="keycap">C+a</code>) selects the
entire buffer.</p><p><span class="guimenu"><strong>Edit</strong></span>><span class="guisubmenu"><strong>More
Selection</strong></span>><span class="guimenuitem"><strong>Select None</strong></span>
(shortcut: <code class="keycap">ESCAPE</code>) deactivates the
selection.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="rect-select"></a>Rectangular Selection</h3></div></div></div><p>Dragging with the <code class="keycap">Control</code> key held down will
create a rectangular selection. Holding down <code class="keycap">Shift</code>
and <code class="keycap">Control</code> while clicking a location in the buffer
will create a rectangular selection from the caret position to the
clicked location.</p><p>Alternatively, invoking
<span class="guimenu"><strong>Edit</strong></span>><span class="guisubmenu"><strong>More
Selection</strong></span>><span class="guimenuitem"><strong>Rectangular
Selection</strong></span> (shortcut: <code class="keycap">A+\</code>) toggles
rectangular selection mode. In rectangular selection mode, dragging
the mouse always creates a rectangular selection, and keyboard
commands that would normally create a range selection create a
rectangular selection instead. A status bar indicator is shown when
this mode is enabled.</p><p>It is possible to select a rectangle with zero width but
non-zero height. This can be used to insert a new column between two
existing columns, for example. Such zero-width selections are shown
as a thin vertical line.</p><p>Inserting text into a rectangular selection repeats the text
going down as many times as necessary, and shifts the selection to
the right. This makes it behave like a <span class="quote">“<span class="quote">tall</span>”</span>
caret.</p><p>Rectangles can be deleted, copied, pasted, and operated on
using ordinary editing commands. If necessary, rectangular
selections are automatically filled in with whitespace to maintain
alignment.</p><p>Rectangular selections can extend beyond the end of a line
into <span class="quote">“<span class="quote">virtual space</span>”</span>. Furthermore, if keyboard
rectangular selection mode is on or if the <code class="keycap">Control</code>
key is being held down, clicking beyond the end of a line will
insert the appropriate amount of whitespace in order to position the
cursor at the clicked location.</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>Rectangular selections are implemented using character
offsets, not absolute screen positions, so they might not behave
as you might expect if a proportional-width font is being used
or if soft wrap is enabled. The text area font can be changed in
the <span class="guibutton"><strong>Text Area</strong></span> pane of the
<span class="guimenu"><strong>Utilities</strong></span>>
<span class="guimenuitem"><strong>Options</strong></span>
dialog box. For information about soft
wrap, see <a class="xref" href="word-wrap.html" title="Wrapping Long Lines">the section called “Wrapping Long Lines”</a>.</p></div></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="multi-select"></a>Multiple Selection</h3></div></div></div><p><span class="guimenu"><strong>Edit</strong></span>><span class="guisubmenu"><strong>More
Selection</strong></span>><span class="guimenuitem"><strong>Multiple
Selection</strong></span> (keyboard shortcut: <code class="keycap">C+\</code>)
turns multiple selection mode on and off. In multiple selection
mode, multiple fragments of text can be selected and operated on
simultaneously, and the caret can be moved independently of the
selection. The status bar indicates if multiple selection mode is
active; see <a class="xref" href="status-bar.html" title="The Status Bar">the section called “The Status Bar”</a>.</p><p>Various jEdit commands behave differently with multiple
selections:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>Commands that copy text place the contents of each
selection, separated by line breaks, in the specified
register.</p></li><li class="listitem"><p>Commands that insert (or paste) text replace each
selection with the entire text that is being
inserted.</p></li><li class="listitem"><p>Commands that filter text (such as <span class="guimenuitem"><strong>Spaces
to Tabs</strong></span>, <span class="guimenuitem"><strong>Range
Comment</strong></span>, <span class="guimenuitem"><strong>Replace in
Selection</strong></span>, and so on) behave as if each block
was selected independently, and the command invoked on each
in turn.</p></li><li class="listitem"><p>Line-based commands (such as <span class="guimenuitem"><strong>Shift Indent
Left</strong></span>, <span class="guimenuitem"><strong>Shift Indent
Right</strong></span>, and <span class="guimenuitem"><strong>Line
Comment</strong></span>) operate on each line that contains at
least one selection.</p></li><li class="listitem"><p>Caret movement commands that would normally deactivate
the selection (such as the arrow keys, while
<code class="keycap">Shift</code> is not being held down), move the
caret, leaving the selection as-is.</p></li><li class="listitem"><p>Some older plugins may not support multiple selection
at all.</p></li></ul></div><p><span class="guimenu"><strong>Edit</strong></span>><span class="guisubmenu"><strong>More
Selection</strong></span>><span class="guimenuitem"><strong>Select None</strong></span>
(shortcut: <code class="keycap">ESCAPE</code>) deactivates the selection
containing the caret, if there is one. Otherwise it deactivates all
active selections.</p><p><span class="guimenu"><strong>Edit</strong></span>><span class="guisubmenu"><strong>More
Selection</strong></span>><span class="guimenuitem"><strong>Invert
Selection</strong></span> (shortcut: <code class="keycap">C+e C+i</code>) selects
a set of text chunks such that all text that was formerly part of a
selection is now unselected, and all text that wasn't, is
selected.</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>Deactivating multiple selection mode while multiple blocks
of text are selected will leave the selections in place, but you
will not be able to add new selections until multiple selection
mode is reactivated.</p></div></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="caret.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="editing.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="keyboard-focus.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Moving The Caret </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> Keyboard Focus </td></tr></table></div></body></html>
