actually, you can remap keys using keymaps. keymaps are translators.. mapping the source key into a string (user speak: textual phrase) which gets sent to all clones... if you want a particular clone to use that string, you load a keymap on it.. which translates the string back to whatever key you want.

ie:
alt-F1 ==> mage.cast.fireball ==> 3

this would require 2 keymaps. the first translates alt-F1 into 'mage.cast.fireball' and the 2nd translates 'mage.cast.fireball' into the '3' key.

using this, you can map any key into any other key... by default, if you do not have a map entry for the string... it is ignored.
