Ive set up my FA On/Off (Z) as a toggle in the game controls.. also chaff ( for me is Left alt) as another example..
I also have Throttle settings 25%(key 7)..50% (8)..75% (9) 100% (0) and 0% or Full Stop (X)
You can totally customise any of your controls from the Game Options Controls section..
The only drawback I have found was after FDEVs added the menu dropdowns..things are buried you just nead to look carefully
Edit sorry I misread.. you have Pad controller.. I use keyboard and J/stick.. sorry
