Re: Carbon.

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.
