I believe to be complete, you should add the vi mode refresh command of inputrc to compliment the emacs refresh command you provided on the following page:
http://www.gnu.org/software/bash/manual/bashref.html#Readline-Init-File-Syntax 8.3 Readline Init File "In addition, the C-x C-r command re-reads this init file, thus incorporating any changes that you might have made to it." This refresh command you provided, won't work in VI mode. It puts the representation of CTRL-x (^x) on the command line, which I assume means it wasn't interpreted as a command character. CTRL-l, (el), the redraw screen command in VI does not cause bash to re-read its inputrc file either. Of course I would be interested to find out what the command is, but more importantly, I think this information should be provided along with the emacs information. Thanks, Kevin
