I have not tried, but you are right -- it will not work on terminal, at least not on remote host, since such terminals do not provide an analog of KeyRelease. OTOH, there are many features in Emacs that do not work in every UI (say, in-line images), but it does not make these features less useful in situations where they do work. > At the time, it seemed like letter-based modifiers were routinely > unclean.

Probably the whole idea that modifier must be a separate key is an atavism of the mechanical design: on a computer keyboard any key can be potentially used as a modifier. The advantage is a reduction of RSI since pressing a key in the home row is easier than pressing the proper modifier. -- Regards, ASK
