OpenDingux-like key mapping option

[gameblabla]

Hello guys,
i see that you revamped the whole key mapping thing, which is great.
Unfortunately the way it needs to be set up right now can be a maintenance burden.
I propose to to make it easier for me and other people expecting an OD mapping the following thing :
Something like an opendingux=1 option to set in the desktop file that would be detected in opkrun could do.

CLEAR
MAP FN       TO KEY     KEY_ESCAPE
MAP START    TO KEY     KEY_ENTER
MAP UP       TO KEY     KEY_UP
MAP LEFT     TO KEY     KEY_LEFT
MAP DOWN     TO KEY     KEY_DOWN
MAP RIGHT    TO KEY     KEY_RIGHT
MAP R        TO KEY     KEY_BACKSPACE
MAP L        TO KEY     KEY_TAB
MAP A        TO KEY     KEY_LEFTCTRL
MAP B        TO KEY     KEY_LEFTALT
MAP X        TO KEY     KEY_LEFTSHIFT
MAP Y        TO KEY     KEY_SPACE
MAP MENU     TO KEY     KEY_HOME

Alternatively, you could have a setting in the desktop file that loads the key mapping from there instead.

Cheers
