Making Buttons Act as Modifiers

[Airgait]

How do I make it so that I can take a button on my CH throttle and make it act like the shift or ctrl key?

For “alt” functions just type ALT
For “ctrl” functions just type CTL
For “shift” fucntions just type SHF

(Looks like you can also put a R or L in front of the function (without a space) if you need to specify Left or Right)
