And looking at the awkwardness that option-as-meta has provoked with
Aquamacs and layouts where option is used as a dead key, he has a
point--that behaviour really breaks on keyboards where option is needed to
generate a character.
But his code already looks at the currently active layout for keys with the
control modifier; it should be possible to check if option + key is bound in
the OS X keymap when such an event comes in, and to pass the corresponding
character to the event handling code rather than option + key. That seems to
me to be the least surprising behaviour.
It’s not practical though, since for most keys option + key generates a
distinct key versus the key on its own in the standard Mac maps. (Things like
œ ˙ é ® þ ¥ for q w e r t z on the German layout.) And there’s no good way
to draw a distinction between option + 4, which generates € and is necessary
for the user, and option + f, which generates ƒ and really isn’t.
The Aquamacs people approach this in a very ad-hoc way, with per-language
tables--see
http://google.com/codesearch?hl=en&lr=&q=file%3Aemulate-mac-keybo...
I suppose though a rule of thumb would be ‘if the character generated with option both:
1. Differs from the character generated without option and
2. Is either ASCII (because our users are programmers) or is necessary to
write the currently active language
then option + char-without-option should generate char-with-option;
otherwise option + char-without-option should generate
M-char-without-option.’ The information on the characters necessary to write
a language is available in the language-specific Quail tables, though it is
incomplete right now.
This is horrible.
