Same key can't be mapped to two different buttons

[GoogleCodeExporter]

I've noticed that it's currently not possible to map a Spectrum key to two 
buttons, like "UP" and "2".

This is handy for making those games that use the "up" direction for both 
jumping and climbing a bit more "console friendly", so it would be nice if the 
emu allowed for that.

It was a programming choise. The Key mapping to more than one button would slow 
down the emulation speed.

I've just managed to trick the emulator into having the same key (9) as Up and 
Button 2, by selecting Interface 2 as the emulated joystick and mapping "9" to 
Button 2.

It doesn't seem to slow down emulation, is there any other reason why this is 
not officially allowed?

Indeed, you can not map two different buttons (e.g. 1 and 2) to the same key 
(e.g. key G), but this rule does not apply to joystick and joypad used as 
joystick.

You can map the movements of the joystick and joypad used as joystick also to 
buttons.
