I can't feel my hands(mostly the left one), I have to look where I place my fingers! So a function that frees up key bindings is of major importance for me. Even if it is just 2 key binds freed, That is a lot for someone who with a Razer Nostromo that is only able to have 16 binds total.

Seriously why don't we? Would it be hard to program? I know we don't have much that requires stealth, but I have several things I mostly do during stealth and things i only do while not. It would be awesome if we had the ability to auto swap this and thereby save a few key bindings. For someone like me, with a somewhat disabled left hand, every key bind that I can save is a huge win.
