[Controls] Add a way to select firing mode with the keyboard (+ a way to fire)

[Bloax]

Currently you can bind a shortcut to use the item in the left/right hand slot of a given unit, but there's no way to select the firing mode after that -  nor any way to confirm where to shoot.
Adding such things would be appreciated, thanks.

if you're shit outta ideas then making the move camera north/south keys scroll between the modes and then have a "(?)confirm(?)" key available that selects the current selection while also serving as the way to confirm where to shoot would work swell

I use the keyboard a lot and having the Q and E keys select objects in the hands is very convenient. Something that would be cool is being able to hit a number key while the action menu is open and select one of the options, with 1 being the top and N being the last, for N options.

So on melee weapons:
1 - Swing
2 - Throw

On grenades:
1 - Prime
2 - Throw

and something similar for guns (can't remember the order).
