/**
* The default input map for an RTextArea. For the most part it is
* exactly that the one for a JTextArea, but it adds a few things.
* Currently, the new key bindings include:
*
*
HOME key toggles between first character on line and first non-
* whitespace character on line.
*
INSERT key toggles between insert and overwrite modes.
*
Ctrl+DELETE key deletes all text between the caret and the end of the
* current line.
*
Ctrl+Shift+Up and Ctrl+Shift+Down move the current line up and
* down, respectively.
*
Ctrl+J joins lines.
*
Ctrl+Z is undo and Ctrl+Y is redo.
*
Ctrl+Up and Ctrl+Down shift the visible area of the text area up and
* down one line, respectively.
*
F2 and Shift+F2 moves to the next and previous bookmarks,
* respectively.
*
Ctrl+F2 toggles whether a bookmark is on the current line.
*
etc.
