I'm having a strange glitch with unbinding keys.
I don't want to use some of the buttons on my mouse for certain things, so I tried to go to the control setup and unbind the keys, but the game (despite doing EXACTLY as the help said) won't unbind.
It wont clear any keys.

I hovered over each key that I wanted to unbind/reset and pressed both delete and backspace multiple times individually, and got no results.

Actually, I didnt think you could unbind keys from the in-game editor. Try removing the keys from the WGAF.cfg file, which is where key binds (and /binds, /alias, and /set commands) are stored.

Ok thank you so much
That fixed it right up!

You can actually use the GUI editor to unbind keys, but its a little bit tricky. If you actually put the key into bind mode by double-clicking it, it will bind to del instead of see it as a remove request. You need to hover/click and del, not click.

As well as Luxens fine suggestion, you can also simply type /bind "key" NONE, replacing "key" with the one you want to unbind. (This can be joystick buttons, mice buttons etc too) Just remember to exit the client properly or changes like this will not stick!
