        <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
        screen-full, 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>><guimenuitem>Options</guimenuitem>;
            see <xref linkend="shortcuts-pane" />.</para>

            <para>By default, the shortcuts are assigned as follows:</para>

    <section 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.
        In addition to the standard text-selection mode, jEdit also allows
        <emphasis role="bold">rectangular selections</emphasis> 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>

        <section>
            <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>><guimenuitem>Select
            All</guimenuitem> (shortcut: <keycap>C+a</keycap>) selects the
            entire buffer.</para>

            <para><guimenu>Edit</guimenu>><guisubmenu>More
            Selection</guisubmenu>><guimenuitem>Select None</guimenuitem>
            (shortcut: <keycap>ESCAPE</keycap>) deactivates the
            selection.</para>
        </section>

        <section 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>><guisubmenu>More
            Selection</guisubmenu>><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>>
                <guimenuitem>Options</guimenuitem>
                dialog box. For information about soft
                wrap, see <xref linkend="word-wrap" />.</para>
            </note>
        </section>

        <section id="multi-select">
            <title>Multiple Selection</title>

            <para><guimenu>Edit</guimenu>><guisubmenu>More
            Selection</guisubmenu>><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

      <title> Keyboard Focus </title>

      <para> When the cursor disappears, that means the text area no longer has focus, and when you type, your keystrokes are probably going somewhere else, such as a dockable. To ensure that the keyboard is focused
      in the textarea, you can always use the mouse and click in it,
      but a more keyboard-friendly way is preferred when you are just about to start typing anyway. For this reason, a number of jEdit's actions
      have a side-effect of focusing on the text area as well. <guimenuitem> View - Toggle Full Screen</guimenuitem> is one example. Some others are listed below:
      </para>

      <para> From the <guimenuitem>View - Scrolling</guimenuitem> submenu:
        <itemizedlist>
        <listitem><para> <guimenuitem>Scroll and Center Caret</guimenuitem> </para></listitem>

        </itemizedlist>
      </para>

      <para> In general, jEdit is a keyboard-friendly editor that is also
      mouse-friendly, so you should never be forced to use a mouse to do anything. </para>

    <section 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 a 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

        <para><guimenu>Edit</guimenu>><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>><guimenuitem>Redo</guimenuitem> (shortcut:

        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 and whether undos are reset when a

        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

        Setting this option will use all open buffers to search for possible

       <tip> <title> MarkerSets </title>
        <para> The MarkerSets plugin is a replacement for the
        built-in Markers feature of jEdit. Markers saved with
        MarkerSets properly update when lines are added or
        removed from a buffer. Furthermore, you can see
        markers from multiple files in the Marker Sets
        dockable. We recommend you use that instead
        of the built-in Markers.
        </para>
        </tip>

        <para>A <firstterm>marker</firstterm> is a pointer to a specific
        location within a buffer, which may or may not have a single-character
        <firstterm>shortcut</firstterm> associated with it. 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 saving can be disabled in the
        <guibutton>General</guibutton> pane of the
        <guimenu>Utilities</guimenu>><guimenuitem>Options</guimenuitem>
        dialog box; see <xref

        <para><guimenu>Markers</guimenu>><guimenuitem>Add/Remove
        Marker</guimenuitem> (shortcut: <keycap>C+e C+m</keycap>) adds a marker
        without a shortcut pointing to the current line. If a marker is already
        set on the current line, the marker is removed instead. If text is
        selected, markers are added to the first and last line of each
        selection.</para>

        <para>Markers are listed in the <guimenu>Markers</guimenu> menu;
        selecting a marker from this menu will move the caret to its
        location.</para>

        <para><guimenu>Markers</guimenu>><guimenuitem>Go to Previous
        Marker</guimenuitem> (shortcut: <keycap>C+e C+COMMA</keycap>) goes to

        <para><guimenu>Markers</guimenu>><guimenuitem>Go to Next
        Marker</guimenuitem> (shortcut: <keycap>C+e C+PERIOD</keycap>) goes to

        Markers</guimenuitem> removes all markers set in the current
        buffer.</para>

        <para>Markers with shortcuts allow for quicker keyboard-based
        navigation. The following commands all prompt for a single-character
        shortcut when invoked. Pressing <keycap>ESCAPE</keycap> instead of
        specifying a shortcut will cancel the operation.</para>

        <para><guimenu>Markers</guimenu>><guimenuitem>Add Marker With
        Shortcut</guimenuitem> (shortcut: <keycap>C+t
        <replaceable>key</replaceable></keycap>) adds a marker with the
        specified shortcut. If marker with that shortcut already exists, it will
        remain in the buffer but lose its shortcut.</para>

        <para><guimenu>Markers</guimenu>><guimenuitem>Go to
        Marker</guimenuitem> (shortcut: <keycap>C+y
        <replaceable>key</replaceable></keycap>) moves the caret to the location
        of the marker with the specified shortcut.</para>

        <para><guimenu>Markers</guimenu>><guimenuitem>Select to
        Marker</guimenuitem> (shortcut: <keycap>C+u
        <replaceable>key</replaceable></keycap>) creates a selection from the
        caret location to the marker with the specified shortcut.</para>

        <para><guimenu>Markers</guimenu>><guimenuitem>Swap Caret and
        Marker</guimenuitem> (shortcut: <keycap>C+k
        <replaceable>key</replaceable></keycap>) moves the caret to the location
        of the marker with the specified shortcut, and moves the marker to the
        former caret position. Invoke this command multiple times to flip
        between two locations in the buffer.</para>

        <para>Lines which contain markers are indicated in the gutter with a
        highlight. Moving the mouse over the highlight displays a tool tip
        showing the marker's shortcut, if it has one. See

            (shortcut: <keycap>C+f</keycap>) displays the search and replace

            <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

            HyperSearch feature.) 

            <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>After selecting the <guibutton>Whole word</guibutton>

            </para>

            <para>To search for special characters (such as newlines or
            non-printable characters), inexact sequences of text, or strings
            that span multiple lines, we use

            Selecting the <guibutton>Regular expressions</guibutton> check
            box allows special characters to be used in the search string.
            Regular expression syntax is described in <xref linkend="regexps"/>.
            If you use (groups) in the search field, you back-reference them
            with $1 through $9 in the replace field. </para>

            <para>The <guibutton>Backward</guibutton> and
            <guibutton>Forward</guibutton> buttons specify the search direction.
            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 <guibutton>Keep dialog</guibutton>
            check box is selected, the dialog box 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

            <para>Clicking <guibutton>Replace & 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

                <para>If the <guibutton>Text</guibutton> button is selected, the

                string.</para>

                <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

            <para>If the <guibutton>Multiple results</guibutton> toggle button is
            selected in the results window, past search results are
            retained.</para>

            <para>Running searches can be stopped in the
            <guimenu>Utilities</guimenu>><guisubmenu>Troubleshooting</guisubmenu>><guimenuitem>I/O
            Progress Monitor</guimenuitem> dialog box.</para>

            <para>Once the results are shown in the Hypersearch dockable, you can
            left-click on a result to jump to the position, or right-click to see some
            "hidden actions". From the top tree-node, for example, you can
            <guimenuitem>Redo Hypersearch</guimenuitem>, and <guimenuitem>Copy to
            Clipboard</guimenuitem>. </para>

        <section>
            <title>Multiple File Search</title>

            <para>Search and replace commands can be performed over an arbitrary
            set of files in one step. The set of files to search is selected
            with a set of buttons in the search dialog box.</para>

            <para>If the <guibutton>Current buffer</guibutton> button is
            selected, only the current buffer is searched. This is the default
            behavior.</para>

            <para>If the <guibutton>All buffers</guibutton> button is selected,
            all open buffers whose names match the glob pattern entered in the
            <guibutton>Filter</guibutton> text field will be searched. See <xref
            linkend="globs" /> for more information about glob patterns.</para>

            <para>If the <guibutton>Directory</guibutton> radio button is
            selected, all files contained in the specified directory whose names
            match the glob will be searched. The directory to search in can
            either be entered in the <guibutton>Directory</guibutton> text
            field, or chosen in a file selector dialog box by clicking the
            <guibutton>Choose</guibutton> button next to the field. If the
            <guibutton>Search subdirectories</guibutton> check box is selected,
            all subdirectories of the specified directory will also be searched.
            Keep in mind that searching through directories containing many
            files can take a long time.</para>

            <para>The <guibutton>Directory</guibutton> and
            <guibutton>Filter</guibutton> text fields remember previously
            entered strings; see <xref linkend="history" /> for details.</para>

            <para>When the search and replace dialog box is opened, the
            directory and file name filter fields are set to their previous
            values. They can be set to match the current buffer's directory and
            file name extension by clicking
            <guibutton>Synchronize</guibutton>.</para>

            <para>Note that clicking the <guibutton>All Buffers</guibutton> or
            <guibutton>Directory</guibutton> radio buttons also selects the
            <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>><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>><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>
        </section>

        <section 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>><guimenuitem>Options</guimenuitem>
            dialog box; see <xref
            linkend="view-pane" />.</para>

            <para><guimenu>Search</guimenu>><guimenuitem>Incremental Search
            Bar</guimenuitem> (shortcut: <keycap>C+COMMA</keycap>) displays the
            search bar if necessary, and gives it keyboard focus. </para>

            <para><guimenu>Search</guimenu>><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. If this command is invoked while there is a
            selection, the selection is placed in the search string
            field instead.</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>><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>><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.</para>
