(The bindings for undo ensure it can be typed with just one shift key on all usual terminals.) * It does not exist at all on ttys. (I don't know whether we can change that on Linux consoles.) Whether constitutes a problem for the undo-redo feature depends on the precise meanings of the two commands. I don't know those details so I can't judge. M-_ is likewise inconvenient because of the need for two shift keys. Defining these keys in addition to the existing binding for 'undo' can't do direct harm. But it may disappoint the users you're trying to help. -- Dr Richard Stallman Chief GNUisance of the GNU Project (https://gnu.org) Founder, Free Software Foundation (https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
