 <sect1 id="caret"><title>Moving The Caret</title>
  <para>
   The simplest way to move the caret is to click the
   mouse at the desired location in the text area. The caret can also be moved
   using the keyboard.
  </para>
  <para>
   The <keycap>LEFT</keycap>, <keycap>RIGHT</keycap>, <keycap>UP</keycap> and
   <keycap>DOWN</keycap> keys move the caret in the respective direction, and
   the <keycap>PAGE_UP</keycap> and <keycap>PAGE_DOWN</keycap> keys move the
   caret up and down one screenful, respectively.
  </para>
  <para>
   When pressed once, the <keycap>HOME</keycap> key moves the caret to the first
   non-whitespace character of the current screen line. Pressing it a second
   time moves the caret to the beginning of the current buffer line. Pressing it
   a third time moves the caret to the first visible line.
  </para>
  <para>
   The <keycap>END</keycap> key behaves in a
   similar manner, going to the last non-whitespace character of the current
   screen line, the end of
   the current buffer line, and finally to the last visible line.
  </para>
  <para>
   If soft wrap is disabled, a <quote>screen line</quote> is the
   same as a  <quote>buffer line</quote>. If soft wrap is enabled,
   a screen line is a section of a newline-delimited buffer line that fits
   within the wrap margin width. See <xref linkend="word-wrap"/>.
  </para>
  <para>
   <keycap>C+HOME</keycap> and
   <keycap>C+END</keycap> move the
   caret to the beginning and end of the buffer, respectively.
  </para>
  <para>
   More advanced caret movement is covered in
   <xref linkend="words" />, <xref linkend="lines" /> and
   <xref linkend="paragraphs" />.
  </para>
  <sidebar><title>The Home and End keys</title>
   <para>
    If you prefer more traditional behavior for the
    <keycap>HOME</keycap> and <keycap>END</keycap> keys, you can reassign
    the respective keyboard shortcuts in the <guibutton>Shortcuts</guibutton>
    pane of the
    <guimenu>Utilities</guimenu>&gt;<guimenuitem>Global Options</guimenuitem>; see <xref linkend="shortcuts-pane"/>.
   </para>
   <para>
    By default, the shortcuts are assigned as follows:
   </para>
   <itemizedlist>
    <listitem><para><keycap>HOME</keycap> is bound to <guimenuitem>Smart
    Home</guimenuitem>.</para></listitem>
    <listitem><para><keycap>END</keycap> is bound to <guimenuitem>Smart
    End</guimenuitem>.</para></listitem>
    <listitem><para><keycap>S+HOME</keycap> is bound to <guimenuitem>Select to Smart
    Home Position</guimenuitem>.</para></listitem>
    <listitem><para><keycap>S+END</keycap> is bound to <guimenuitem>Select to Smart
    End Position</guimenuitem>.</para></listitem>
   </itemizedlist>
   <para>
    However you can rebind them to anything you want, for example, various
    combinations of the following, or indeed any other command or macro:
   </para>
   <itemizedlist>
    <listitem><para><guimenuitem>Go to Start/End of White Space</guimenuitem>.</para></listitem>

 </sect1>
 <sect1 id="selection"><title>Selecting Text</title>
  <para>
   A <firstterm>selection</firstterm> is a block of text marked for further
   manipulation. Range selections are equivalent to selections in most other text editors; they cover text between two points in a buffer. jEdit also allows rectangular selections that cover a rectangular area (some text editors refer to these as <quote>column selections</quote>). Furthermore, several chunks of text can be
   selected and operated on simultaneously.
  </para>
  <sect2><title>Range Selection</title>
  <para>
   Dragging the mouse creates a range selection from where the mouse was
   pressed to where it was released.
   Holding down <keycap>Shift</keycap> while clicking a location in the
   buffer will create a selection from the caret position to the clicked
   location.
  </para>
  <para>
   Holding down <keycap>Shift</keycap> in addition to a caret movement key
   (<keycap>LEFT</keycap>, <keycap>UP</keycap>, <keycap>HOME</keycap>, etc) will
   extend a selection in the specified direction.
  </para>
  <para>
   <guimenu>Edit</guimenu>&gt;<guimenuitem>Select All</guimenuitem> (shortcut:
   <keycap>C+a</keycap>) selects the
   entire buffer.
  </para>
  <para>
   <guimenu>Edit</guimenu>&gt;<guisubmenu>More Selection</guisubmenu>&gt;<guimenuitem>Select None</guimenuitem> (shortcut:
   <keycap>ESCAPE</keycap>) deactivates the selection.
  </para>
  </sect2>
  <sect2 id="rect-select"><title>Rectangular Selection</title>
   <para>
    Dragging with the <keycap>Control</keycap> key held down will create a
    rectangular selection. Holding down
    <keycap>Shift</keycap> and <keycap>Control</keycap> while clicking a
    location in the buffer will create a rectangular selection from the caret
    position to the clicked location.
   </para>
   <para>
    Alternatively, invoking
    <guimenu>Edit</guimenu>&gt;<guisubmenu>More
    Selection</guisubmenu>&gt;<guimenuitem>Rectangular Selection</guimenuitem>
    (shortcut: <keycap>A+\</keycap>)
    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.
   </para>
   <para>
    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.
   </para>
   <para>
    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 <quote>tall</quote> caret.
   </para>
   <para>
    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.
   </para>
   <para>
    Rectangular selections can extend beyond the end of a line into
    <quote>virtual space</quote>. Furthermore,
    if keyboard rectangular selection mode is on or if the
    <keycap>Control</keycap> 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.
   </para>
   <note>
    <para>
     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
     <guibutton>Text Area</guibutton> pane of the
     <guimenu>Utilities</guimenu>&gt;<guimenuitem>Global Options</guimenuitem>
     dialog box. For information about soft wrap,
     see <xref linkend="word-wrap" />.
    </para>

  <sect2 id="multi-select"><title>Multiple Selection</title>
   <para>
    <guimenu>Edit</guimenu>&gt;<guisubmenu>More
    Selection</guisubmenu>&gt;<guimenuitem>Multiple Selection</guimenuitem>
    (keyboard shortcut: <keycap>C+\</keycap>)
    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 <xref linkend="status-bar"/>.
   </para>
   <para>
    Various jEdit commands behave differently with multiple selections:
   </para>
   <itemizedlist>
    <listitem><para>Commands that copy text place the contents of
    each selection, separated by line breaks, in the specified register.
    </para></listitem>
    <listitem><para>Commands that insert (or paste) text replace each selection
    with the entire text that is being inserted.</para></listitem>
    <listitem><para>Commands that filter text (such as <guimenuitem>Spaces to
    Tabs</guimenuitem>, <guimenuitem>Range Comment</guimenuitem>,
    <guimenuitem>Replace in Selection</guimenuitem>, and so on) behave as if
    each block was selected independently, and the command invoked on each in
    turn.</para></listitem>
    <listitem><para>Line-based commands (such as <guimenuitem>Shift Indent
    Left</guimenuitem>, <guimenuitem>Shift Indent Right</guimenuitem>, and
    <guimenuitem>Line Comment</guimenuitem>) operate on each line that contains
    at least one selection.
    </para></listitem>
    <listitem><para>Caret movement commands that would normally deactivate the
    selection (such as the arrow keys, while <keycap>Shift</keycap> is not being
    held down), move the caret, leaving the selection as-is.</para></listitem>
    <listitem><para>Some older plugins may not support multiple selection at
    all.</para></listitem>
   </itemizedlist>
   <para>
    <guimenu>Edit</guimenu>&gt;<guisubmenu>More
    Selection</guisubmenu>&gt;<guimenuitem>Select None</guimenuitem>
    (shortcut: <keycap>ESCAPE</keycap>) deactivates the selection containing the
    caret, if there is one. Otherwise it deactivates all active selections.
   </para>
   <para>
    <guimenu>Edit</guimenu>&gt;<guisubmenu>More
    Selection</guisubmenu>&gt;<guimenuitem>Invert Selection</guimenuitem>
    (shortcut: <keycap>C+e C+i</keycap>) 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.
   </para>
   <note>
    <para>
     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.
    </para>
   </note>
  </sect2>
 </sect1>
 <sect1 id="entering-text"><title>Inserting and Deleting Text</title>
  <para>
   Text entered at the keyboard is inserted into the buffer. In overwrite mode, which can be toggled by pressing <keycap>INSERT</keycap>, one character is deleted from in
   front of the caret position for every character that is inserted. The caret is
   drawn as horizontal line while overwrite
   mode is active. The status bar also indicates if overwrite mode is active; see
   <xref linkend="status-bar"/> for details.
  </para>
  <para>
   Inserting text while there is a selection will replace the selection
   with the inserted text.
  </para>
  <para>
   When inserting text, the <keycap>TAB</keycap> and
   <keycap>ENTER</keycap> keys might
   not behave entirely like you expect because  of various indentation
   features; see <xref linkend="indent" /> for details.
  </para>
  <para>
   The simplest way to delete text is with the
   <keycap>BACKSPACE</keycap> and <keycap>DELETE</keycap> keys. If nothing is
   selected, they delete the character before or after the caret,
   respectively. If a selection exists, both delete the
   selection.
  </para>
  <para>
   More advanced deletion commands are described in
   <xref linkend="words" />, <xref linkend="lines" /> and
   <xref linkend="paragraphs" />.
  </para>
 </sect1>
 <sect1 id="undo-redo"><title>Undo and Redo</title>
  <para>
   <guimenu>Edit</guimenu>&gt;<guimenuitem>Undo</guimenuitem> (shortcut: <keycap>C+z</keycap>) reverses the
   most recent editing command. For example, this can be
   used to restore unintentionally deleted text. More complicated operations,
   such as a search and replace, can also be undone.
  </para>
  <para>
   If you undo too many changes,
   <guimenu>Edit</guimenu>&gt;<guimenuitem>Redo</guimenuitem> (shortcut:
   <keycap>C+e C+z</keycap>) can restore
   the changes again. For example, if some
   text was inserted, <guimenuitem>Undo</guimenuitem> will remove it from the
   buffer. <guimenuitem>Redo</guimenuitem> will insert it again.
  </para>
  <para>
   By default, the last 100 edits is retained; older edits cannot be undone.
   The maximum number of undos can be changed in the <guibutton>Editing</guibutton> pane
   of the <guimenu>Utilities</guimenu>&gt;<guimenuitem>Global
   Options</guimenuitem> dialog box; see <xref linkend="editing-pane"/>.
  </para>
 </sect1>
 <sect1 id="words"><title>Working With Words</title>
  <para>
   <keycap>C+LEFT</keycap> and <keycap>C+RIGHT</keycap>
   move the caret a word at
   a time. Holding down <keycap>Shift</keycap> in addition to the above
   extends the selection a word at a time.
  </para>
  <para>
   A single word can be selected by double-clicking with the mouse,
   or using the
   <guimenu>Edit</guimenu>&gt;<guisubmenu>More
   Selection</guisubmenu>&gt;<guimenuitem>Select
   Word</guimenuitem> command (shortcut: <keycap>C+e w</keycap>).
   A selection that begins and ends on word boundaries can be created by
   double-clicking and dragging.
  </para>
  <para>
   <keycap>C+BACKSPACE</keycap> and <keycap>C+DELETE</keycap>
   delete the word
   before or after the caret, respectively.
  </para>
  <para>
   <guimenu>Edit</guimenu>&gt;<guimenuitem>Complete Word</guimenuitem> (shortcut: <keycap>C+b</keycap>) locates
   possible completions for the word at the caret, first by looking in the
   current edit mode's syntax highlighting
   keyword list, and then in the current buffer for words that begin with the
   word at the caret. This serves as a very basic code completion feature.
  </para>
  <para>
   If there is only one completion, it will be inserted into the buffer
   immediately.
  </para>
  <para>
   If multiple completions were found, the longest common prefix is inserted into the buffer, and a popup is shown below
   the caret position listing the completions.
  </para>
  <para>
   To insert a completion from the list, either select it using the <keycap>UP</keycap> and <keycap>DOWN</keycap> keys and
   press <keycap>ENTER</keycap>, press a digit to insert one of the first
   ten completions (1 is the first completion; 9 is the 9th; 0 is the 10th),
   or click the desired completion with the mouse. To close the popup without inserting a
   completion, press <keycap>ESCAPE</keycap>.
  </para>
  <para>
   Typing while the popup is
   visible will automatically update the popup and narrow the set of
   completions as necessary.
  </para>
  <para>
   <guimenu>Edit</guimenu>&gt;<guimenuitem>Word Count</guimenuitem>

 <sect1 id="text-transfer"><title>Transferring Text</title>
  <para>
   jEdit provides a rich set of commands for moving and copying text. Commands
   are provided for moving chunks of text from buffers to
   <firstterm>registers</firstterm> and vice-versa. A register is a holding area
   for an arbitrary length of text, with a single-character name. Most other programs can only transfer text to and from the system clipboard; in jEdit, the system clipboard is just another register, with the special name <filename>$</filename>.
  </para>

   </para>
   <para>
    The <guimenuitem>Cut</guimenuitem> and <guimenuitem>Copy</guimenuitem>

    the former clipboard contents, followed by a newline, followed by the
    selected text.

  <sect2 id="quick-copy"><title>Quick Copy</title>
   <para>
    The quick copy feature is usually found in Unix text editors.
    Quick copy is disabled by default, but it can be enabled in the

    <guimenu>Utilities</guimenu>&gt;<guimenuitem>Global Options</guimenuitem>
    dialog box.
   </para>
   <para>
    The quick copy feature is accessed using the middle mouse button. If you do not have a three-button mouse, then either <keycap>Alt</keycap>-click (on Windows and Unix) or <keycap>Option</keycap>-click (on MacOS X). The quick copy feature enables the following behavior:
   </para>
   <itemizedlist>
    <listitem><para>
    Clicking the middle mouse button in the text area inserts the most recently
    selected text at the clicked location.
    If you only have a two-button mouse, you can click the left mouse button
    while holding down <keycap>Alt</keycap> instead of middle-clicking.
   </para></listitem>
   <listitem><para>
    Dragging with the middle mouse button
    creates a selection without moving the
    caret. As soon as the mouse button is released, the selected text is
    inserted at the caret position and the selection is deactivated.
    A message is shown in the status bar while text is being selected to
    remind you that this is not an ordinary selection.
   </para></listitem>
   <listitem><para>
    Holding down <keycap>Shift</keycap> while clicking the middle mouse

    If jEdit is being run under Java 2 version 1.4 on Unix, you will be
    able to transfer text with other X Windows applications using the
    quick copy feature. On other platforms and Java versions, the contents

   Markers are persistent; they are saved to
   <filename>.<replaceable>filename</replaceable>.marks</filename>, where
   <filename><replaceable>filename</replaceable></filename> is the name of the
   buffer. (The dot prefix
   makes the markers file hidden on Unix systems.) Marker

   <para>
    The search string can be entered in the <guibutton>Search for</guibutton>
    text field. This text field remembers previously entered strings; see
    <xref linkend="history" /> for details.
   </para>
   <para>
    If text was selected in the text area and the selection
    does not span a line break, the selected text becomes the default search
    string.
   </para>
   <para>
    If the selection spans a line break, the
    <guibutton>Search in Selection</guibutton>
    and <guibutton>HyperSearch</guibutton>
    buttons will be pre-selected, and the search string field will be
    initially blank. (See <xref linkend="hypersearch"/> for information about
    the HyperSearch feature.)
    <!-- Note that finding the next or previous
    occurrence cannot be constrained to a selected range; only
    replacement and HyperSearch can be (see <xref linkend="hypersearch" />). -->
   </para>
   <para>
    Selecting the <guibutton>Ignore
    case</guibutton> check box makes the search case insensitive -
    for example, searching for
    <quote>Hello</quote> will match <quote>hello</quote>, <quote>HELLO</quote>
    and <quote>HeLlO</quote>.
   </para>
   <para>
    Selecting the <guibutton>Regular expressions</guibutton> check
    box allows a regular expression to be used in the search string. Regular
    expressions can
    match inexact sequences of text that optionally span more than one line.
    Regular expression syntax is described in
    <xref linkend="regexps" />.
   </para>
   <para>
    The <guibutton>Backward</guibutton> and <guibutton>Forward</guibutton>

    Note that regular expressions can only be used when
    searching in a forward direction.
   </para>
   <para>
    Clicking <guibutton>Find</guibutton> will locate the next occurrence of
    the search string (or previous occurrence, if
    searching backwards). If the

    will remain open after the search string has been located; otherwise,
    it will close.
   </para>
   <para>
    If no occurrences could be found and the
    <guibutton>Auto wrap</guibutton> check box is selected, the search will
    automatically restart from the beginning of the buffer (or the end, if
    searching backwards).
    If <guibutton>Auto wrap</guibutton> is not selected, a confirmation dialog
    box is shown before restarting the search.
   </para>
   <para>
    <guimenu>Search</guimenu>&gt;<guimenuitem>Find Next</guimenuitem> (shortcut:

  <sect2><title>Replacing Text</title>
   <para>
    The replace string text field of the search dialog
    remembers previously entered strings;
    see <xref linkend="history" /> for details.
   </para>
   <para>
    Clicking <guibutton>Replace &amp; Find</guibutton> will perform a
    replacement in the current selection and locate the next occurrence of the
    search string. Clicking <guibutton>Replace All</guibutton> will replace all
    occurrences of the search string with the replacement string in the current
    search scope (which is either the selection, the current buffer, or a set of
    buffers, as specified in the search and replace dialog box).
   </para>
   <para>
    Occurrences of the search string can be replaced with either a replacement
    string, or the return value of a BeanShell script snippet. Two radio buttons
    in the search and replace dialog box select between the two replacement
    modes, which are described in detail below.
   </para>
   <sect3><title>Text Replace</title>
    <para>
     If the <guibutton>Text</guibutton> button is selected,
     the search string is simply replaced with the replacement
     string.

    <para>
     If regular expressions are enabled, positional parameters
     (<literal>$0</literal>, <literal>$1</literal>, <literal>$2</literal>, and so
     on) can be used to insert the contents of matched subexpressions in the
     replacement string; see <xref linkend="regexps" /> for more information.
    </para>
    <para>
     If the search is case-insensitive, jEdit attempts to modify the
     case of the replacement string to match that of the particular instance
     of the search string being replaced. For example, searching
     for <quote>label</quote> and replacing it with <quote>text</quote>, will
     perform the following replacements:
    </para>
    <itemizedlist>
     <listitem><para><quote>String label</quote> would become <quote>String text</quote>
     </para></listitem>
     <listitem><para><quote>setLabel</quote> would become <quote>setText</quote>
     </para></listitem>
     <listitem><para><quote>DEFAULT_LABEL</quote> would become <quote>DEFAULT_TEXT</quote>
     </para></listitem>
    </itemizedlist>
   </sect3>
   <sect3><title>BeanShell Replace</title>
    <para>
     In BeanShell replacement mode, the search string is replaced with the return
     value of a BeanShell snippet. The following predefined variables can be
     referenced in the snippet:
    </para>
    <itemizedlist><listitem><para><varname>_0</varname> -- the text to be
    replaced</para>
    </listitem><listitem><para><varname>_1</varname> - <varname>_9</varname> --
    if regular expressions are enabled, these contain the values of matched
    subexpressions.
    </para></listitem></itemizedlist>

    <guibutton>HyperSearch</guibutton> check box
    since that is what you would want, most of the time.
    However, the <guibutton>HyperSearch</guibutton> check box can be unchecked, for stepping through search results in multiple files one at a time.
   </para>
   <para>
    Two convenience commands are provided for performing multiple file searches.
   </para>
   <para>
    <guimenu>Search</guimenu>&gt;<guimenuitem>Search in Open
    Buffers</guimenuitem> (shortcut: <keycap>C+e C+b</keycap>) displays
    the search dialog box and selects the <guibutton>All
    buffers</guibutton> button.
   </para>
   <para>
    <guimenu>Search</guimenu>&gt;<guimenuitem>Search in Directory</guimenuitem>
    (shortcut: <keycap>C+e C+d</keycap>) displays
    the search dialog box and selects the
    <guibutton>Directory</guibutton> button.
   </para>
  </sect2>
  <sect2 id="search-bar"><title>The Search Bar</title>
   <para>
    The search bar feature provides a convenient way to search in the current
    buffer without
    opening the search dialog box. The search bar does not support replacement or multiple file search. Previously entered strings can be recalled in the
    search bar with the <keycap>Up</keycap> and <keycap>Down</keycap> arrow
    keys; see <xref linkend="history" />.
   </para>
   <para>
    By default, the search bar remains hidden until one of the quick search
    commands (described below) is invoked; however you can choose to have it
    always visible in the <guibutton>View</guibutton> pane of the
    <guimenu>Utilities</guimenu>&gt;<guimenuitem>Global Options</guimenuitem>
    dialog box; see <xref linkend="view-pane"/>.
   </para>
   <para>
    <guimenu>Search</guimenu>&gt;<guimenuitem>Incremental Search Bar</guimenuitem>
    (shortcut: <keycap>C+COMMA</keycap>)
    displays the search bar if necessary, and gives it keyboard focus.
    If this command is invoked while there is a selection, the selection is
    placed in the search string field.
   </para>
   <para>
    <guimenu>Search</guimenu>&gt;<guimenuitem>Incremental Search
    for Word</guimenuitem>
    (shortcut: <keycap>A+COMMA</keycap>)
    behaves like the above command except it places the word at the caret in
    the search string field.
   </para>
   <para>
    Unless the <guibutton>HyperSearch</guibutton> check box is selected, the
    search bar will perform an <firstterm>incremental search</firstterm>.
    In incremental search mode, the first occurrence of the search
    string is located in the current buffer as it is being typed.
    Pressing <keycap>ENTER</keycap> and <keycap>S+ENTER</keycap>
    searches for the next and previous occurrence, respectively.
    Once the desired occurrence has been located, pressing <keycap>ESCAPE</keycap>
    returns keyboard focus to the text area. Unless the search bar is set to be
    always visible (see above), pressing <keycap>ESCAPE</keycap> will also hide
    the search bar.
   </para>
   <note>
    <para>
     Incremental searches cannot be not recorded in macros. If your macro
     needs to perform a search, use the
     search and replace dialog box instead. See <xref linkend="using-macros" />
     for information about macros.
    </para>
   </note>
   <para>
    <guimenu>Search</guimenu>&gt;<guimenuitem>HyperSearch Bar</guimenuitem>
    (shortcut: <keycap>C+PERIOD</keycap>)
    displays the search bar if necessary, gives it keyboard focus,
    and selects the <guibutton>HyperSearch</guibutton> check box.
    If this command is invoked while there is a selection, the selected text
    will be searched for immediately and the search bar will not be shown.
   </para>
   <para>
    If the <guibutton>HyperSearch</guibutton> check box is
    selected, pressing <keycap>Enter</keycap> in the search string field
    will perform a HyperSearch in the current buffer.
   </para>
   <para>
    <guimenu>Search</guimenu>&gt;<guimenuitem>HyperSearch
    for Word</guimenuitem>
    (shortcut: <keycap>A+PERIOD</keycap>)
    performs a HyperSearch for the word at the caret. This command does not
    show the search bar or give it keyboard focus.
