I have been able to access the keymap and keyboard (CTRL+F1) to assist in programming my Thrustmaster 1600M for use in TIEFighter. But I have a basic and what seems like an obvious question: How do I create Uppercase letters using keymapper? I have tried clicking "Shift" and then "hold" and then the lowercase letter, but this does not seem to work. It defaults back to the lowercase command. Thanks in advance for any help

I don't think the game differentiate between upper- and lowercase and it is either "a" or "Shift-a" for example, or I just simply don't understand what you're trying to do.
