Why not use register-read-with-preview (uses read-key), which seems
like the function specifically made for this?
Other possibilities are read-multiple-choice (currently uses
read-char, but maybe should be changed to read-event, see Bug#32257),
read-answer (uses read-from-minibuffer + keymap) which is new in
master, but I plan to backport to emacs-26 soon (see Bug#31782).
