rluserman: Readline vi Mode

 
 1.5 Readline vi Mode
 ====================
 
 While the Readline library does not have a full set of 'vi' editing
 functions, it does contain enough to allow simple editing of the line.
 The Readline 'vi' mode behaves as specified in the POSIX standard.
 
    In order to switch interactively between 'emacs' and 'vi' editing
 modes, use the command 'M-C-j' (bound to emacs-editing-mode when in 'vi'
 mode and to vi-editing-mode in 'emacs' mode).  The Readline default is
 'emacs' mode.
 
    When you enter a line in 'vi' mode, you are already placed in
 'insertion' mode, as if you had typed an 'i'.  Pressing <ESC> switches
 you into 'command' mode, where you can edit the text of the line with
 the standard 'vi' movement keys, move to previous history lines with 'k'
 and subsequent lines with 'j', and so forth.
