Camera controls are now modifiable! You're no longer stuck with WASD QE, which must have been frustrating on international keyboard layouts.
Type 'Binds' into the console to see the syntax.
This will bind the up axis of the camera to the W key (the default):
bind up = w
Put a different letter key after the equals sign to change that keybind!
If you want to do non-letter keys, you can find the full list of strings that *should* work here, under the "properties" section:
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/KeyCode.html
The axes are referred to as [up, down, right, left, forward, back]. So again, the syntax is
bind [axis] = [keycode]
Thank you to Borg for bringing this to my attention. Hope this helps!
