(I'm going through old bug reports that unfortunately got little response at the time.) I'm not sure I quite understand this bug report -- read-event/key seems to return the values described, but the arrow keys work fine for me in Emacs 28 with -nw (on Debian/bullseye). So is this a problem that has gone away in the years since this was reported, or do you still see these issues? -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
