- function cedit(s)
- %CEDIT Set command line edit/recall facility parameters.
- % CEDIT('off') turns off command line recall/edit.
- % CEDIT('on') turns command line recall/edit back on.
- % CEDIT('vms') chooses VMS key definitions.
- % CEDIT('emacs') returns to the default Emacs key definitions.
- % Here is a table that shows which keystrokes are available
- % using the command line editor:
- %
- % Previous line: ^p
- % Next line: ^n
- % One character left: ^b
- % One character right: ^f
- % Cursor word left: esc b, ^l
- % Cursor word right: esc f, ^r
- % Cursor to beginning of line: ^a
- % Cursor to end of line: ^e
- % Cancel line: ^u
- % In place delete: ^d
- % Insert toggle: ^t
- % Delete to end of line: ^k
- %
- % Type CEDIT.M for more information.
- % The 'emacs' option is always in effect for MS-Windows, in
- % addition to its normal fixed key bindings.

- % Note: In addition to the above definitions, the following functions
- % are ALWAYS attached to standard keys via termcap:
- % One character left - Left Arrow
- % One character right - Right Arrow
- % Previous line - Up Arrow
- % Next line - Down Arrow
- %
- % The following functions are always attached to their 'stty' definitions:
- % Delete Left (i.e. backspace operation) - STTY 'ERASE' Key
- % If ERASE key is <BS> (stty ^H) then <DEL> does in-place delete.
- % If ERASE key is <DEL> (stty ^?) then <BS> does in-place delete.
