^R was for reprint as you see in stty -a. Useful for remembering what you've already typed when some background program clobbers your input. I think it changed in 5.9 or 6.0. Bash has done the history search thing as long as I can remember. I often type EDITOR=vi svn commit since svn defaults to an error message instead of some fallback editor. This has the unfortunate side effect of breaking all the keybindings until I remember to type set -o emacs. What works is to set EDITOR in your profile, then set -o emacs. The other order will result in the shell changing to vi mode. Or we could all set EDITOR to ed, the STANDARD text editor. Martin
