That explains why '<f12> b' works

    Juri> Do you have an idea how to do the right thing and to guess the user's

I guess it should be possible to find out what the 'original' key
pressed was. <time passes> How about the below? I guess it changes the
behaviour when you have a command bound to two keys in the same repeat
map, and you use the 'wrong' one to repeat (but I could argue that
people creating such keymaps should use the 'repeat-check-key'
property)

Ramesh,

(put 'my-cmd-a 'repeat-check-key 'no)
(put 'my-cmd-b 'repeat-check-key 'no)

should do the right thing for you regardless of whether we change
Emacs.
