AGOS: Waxworks: Add hotkey for switching to fighting

A few times in the game the monsters have gotten the jump on me and if there was a hotkey, like "F" (or some other key) or maybe even right click for switching to the currently equipped weapon, and then back to the movement arrow, that would make fighting a lot more successful (less tedious).

The fighting button is what does this and it is the one with the two swords.

There are other buttons, but I think mapping the fighting one would be the most useful.

The original interpreter doesn't have this.
