CUSTOM KEY(S) FOR CALLING GSX MENU

[schiphol104]

First of all compliments. Lots of things work. Yes their are a lot of bugs, but it is mighty complicated. FSDT will work on it without doubt. I had only 1 passenger in Gibraltar. The airline company is bankrupt.
But my actual question is: is there a possibility to choose your own key (also on X52?) for calling the menu???
Thanks Eef Klaassen.

The GSX manual explains how to customize the key used to call GSX. It must be a key, not a joystick button, but you can surely use the X52 software to assign a key to a button.
