Yes, this is a thing with SWTOR and LOTRO and probably some other games, EQ2 maybe.

If the Key Combination being sent to this game includes a modifier -- Alt, Ctrl, or Shift -- then in order for the game to correctly process that modifier, the "Hold any Keystroke Actions while the Hotkey is held" option must be set to ON. Otherwise, the modifier may not still be held when the game decides it's time to check the state, and it will only interpret F1 in a Ctrl+F1.

Keystroke Actions in the same Step of a Mapped Key must be combined in order to all be Held. So if you've got Ctrl+F1 and Alt+F1 in the same step, going to the same Target (window..), the game is going to get Ctrl+F1+Alt+F1, all held down at once, before any of those buttons are released when you let go of the Hotkey. It's going to end up Ctrl+F1 and Ctrl+Alt+F1, or depending on the design of the game (I can imagine this going either way for different games) it may only interpret Ctrl+F1, or it may only interpret Ctrl+Alt+F1.

Also, if these keys need to go to the current window, any modifier keys that you are currently holding at the time may be interpreted by the game. (Because of the Hold flag on the Mapped Key)


I've never really liked this issue with certain games, maybe I can fiddle with something.
