logic prevents the same key (NULL) to be assigned to different functions.
first match (function; the order in the keymap file is not important, but the
order in which the functions are parsed in the code) counts. if the key is
already assigned to a diffrent function the laster function gets it's
default key added.

the following untedted pathc may work - or break remapping in total.
