All controls should be able to be customizable.
Some, such as F1-F12 and the number keys (to the right of the ~ key) are reserved, and the bindings for those keys cannot be modified.
Known keys that are not able to be modified:
- Numbers to the right of the ~ key
- F1 through to F12
- Splendid Camera controls
Please add any that are missing to help out the developers.
