	editing-mode can be set to either emacs or vi.
	
keymap (emacs)
	Set  the  current  readline  keymap.
	The set of legal keymap names is emacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move, vi-command, and vi-insert.
	vi is equivalent to vi-command; emacs is equivalent to emacs-standard.
	The default value is emacs.  The value of editing-mode also affects the default keymap.
