I've been searching for a solution for this to no avail. The custom shortcut key CTRL-\ for the XR2's retro engine doors isn't working for me. I know I can open/close the doors from the 2D cockpit but I'd rather use the shortcut key command. The other custom shortcut keys work fine. I've tried multiple keyboards. I'm actually trying to link the shortcut command to my joystick using the Joy2Key software so I know it really has nothing to do with the keyboard. Has anyone else experienced this? Thanks!
