C+LEFT and C+RIGHT move the
        caret a word at a time. Holding down Shift in addition
        to the above extends the selection a word at a time.
A single word can be selected by double-clicking with the mouse,
        or using the >> command
        (shortcut: C+e w). A selection that begins and ends on
        word boundaries can be created by double-clicking and dragging.
C+BACKSPACE and C+DELETE delete
        the word before or after the caret, respectively.
> (shortcut: C+b) 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.
If there is only one completion, it will be inserted into the buffer immediately.
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.
To insert a completion from the list, either select it using the
        UP and DOWN keys and press
        ENTER, 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 ESCAPE.
Typing while the popup is visible will automatically update the popup and narrow the set of completions as necessary.
The default word completion uses the visible buffers (buffers being shown in an EditPane) to find completions. The set of possible words can be expanded by enabling the option. Setting this option will use all open buffers to search for possible completions. Note, this can degrade completion performance if many buffers are open.
> displays a dialog box with the number of characters, words and lines in the current buffer.
The default behavior of the C+LEFT,
            C+RIGHT, C+BACKSPACE and
            C+DELETE commands is to stop both at the beginning
            and the end of each word. Normally, a word is a sequence of
            alphanumerics, but you can add other characters as part of
            what jEdit considers to be a 'word', set on a global or mode basis
            from .
            In addition, this behavior can be changed by remapping
            these keystrokes to alternative actions whose names end with
             in the
             pane of the
            >
            dialog box; see the section called “The Shortcuts Pane”.
