I must come back to you about disabling the control keys, but:
So exactly how do I assign these keys? Can someone walk me through it?
Ex: Change the first hotkey from "1" to "F12"
1. Hold down left Control and click on the "1" of the first hotkey
2. The "1" will now start to blink
3. Tap "F12"
4. The "1" will stop blinking, and change to "F12"
To cancel a change, click the mouse anywhere. To remove without adding a new button, tap Backspace
To bind the hotkey to a mouse button, do the same as above, but click on the mouse button instead - but for the mouse buttons to be bound, you must hold down left control when clicking them.
To bind a key to a completely unbound hotkey, hold down left control and click on where the key would have been displayed. It will now blink with a "?".
