It seems that the Linux keyboard layout is very old, and too few keycodes were envisaged for existing key combinations. This led to Meta_Tab being used sometimes for and sometimes (wrongly in my view) for . Thomas Dickey has tracked down a bug "fix" in SuSE GNU/Linux from (I think it was) 2007 where someone recorded that the change was made to assigning to Meta_Tab, but without noting down any reasons. TD also justified the change in ncurses-6.3 by saying that the key assignment had come to prevail in the main GNU/Linux distributions, and this change merely reflects current practice. > The discussion should also include Thomas Dickey , > the ncurses maintainer. Thomas Dickey is already in the conversation, having answered a post to bug-ncurses@gnu.org with Subject: Emacs difficulties in linux console with ncurses-6.3 caused by kcbt=\E^I. That thread was cross-posted to emacs-devel. The conversation has not yet been resolved. > -- > Dr Richard Stallman (https://stallman.org) > Chief GNUisance of the GNU Project (https://gnu.org) > Founder, Free Software Foundation (https://fsf.org) > Internet Hall-of-Famer (https://internethalloffame.org) -- Alan Mackenzie (Nuremberg, Germany).
