Allow more than one key to be assigned for a single function

There are way more important issues going on with CF right now that really need to be attended to, but in the mean time, Id like to see this ability implemented & I wouldnt think it should be any problem to do so.

Lots of games you see where you can assign more than one key to any single operation, instead of allowing only one key. For example Id like to be able to keep my "W" key as move forward, but also have another key assigned to walking forward as well.

Reason I say this, I just got a new mouse with a side button. Sometimes during play I have to use my left hand for something. Taking a drag off my cigarette, grabing a quick drink, answering the phone; etc.

Itd be cool & more convenient to just be able to use this side button on my mouse to walk forward when I want to. I checked & the game already recognizes this side button if I wanted to assign it, but the way it is now, I can only have the side button, or "W", not both.

This would be especially useful during the begining of each match when theres really nothing serious going on & youre just trying to get to wherever you want to go before the real action starts.

Yeah this isnt all that important, but would still be nice to have.
