All four of my arrow keys move the Camera right.
If I rebind them it works until i restart Xenonauts.
Then they are back to only going right.
I also have used the Del and Page Down Keys for Rolling Right and Left.
Again it works until a restart.
In the Rebinding/Options Screen the key names of the arrow keys, Del and Page Down are not shown.
I have bound the End Key to Melee and it works but it shows the # Key in the Options Screen.
Here a Screenshot of the Options Screen. After I bound the Keys.
