[KBM] Remap Key to Mouse Click

[vinnyjames]

Be nice if keyboard keys could be re-assigned to mouse keys. E.g. I like to use F1 to send a mouse left mouse click.

If we make this, we should look that is also works in the opposite direction.

Please, yes!
That would be very useful in combination with eye tracking software.
