Technically, that would be Meta-D (even if your Meta key has "Alt" printed
on it).

Alt-<char> produces chr(ord(char)+128); Meta-<char> produces "\e"+char.

At least, that's the historical distinction between Meta and Alt. With
xterm, the behaviour is configurable via the resources altIsNotMeta,
altSendsEscape and metaSendsEscape.

None of which has anything to do with trying to feed a GUI program key
events via stdin ...
