Hm, I think I was confused thinking that TAB was the same as C-i on a tty, and thinking about how you can't bind C-I in non-graphical environments. But I see that instead I get TAB when I run under a tty -- both on the TAB key and when hitting C-i? And S-TAB gives me a backtab event? But C-S-i gives me a TAB event.

But if you M-: (global-set-key (kbd "C-M-S-o") 'previous-line) and then hit C-M-S-o, then Emacs will try to execute the command bound to C-M-o, so at least there it makes sense for the interactive spec to downcase, doesn't it? Because that will at least bind something that can be executed with the same chord that the user hit (even if it wasn't the chord the user expected). But I see that M-x global-set-key does the same under guis, and it doesn't make much sense there. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
