I have some buttons wired to a USB encoder. I'm trying to make the buttons do functions for my simulator. I have used all the F- keys. They all seem to work. Now I want to use the F- kays with the Cntl or Alt key. When i press both keys att he same time they don't work. When i press and hold the Alt key then the F key it works as expected. Due to wiring of my buttons the Alt key can't be held down.
Is there any way i can program the script so i can press and hold the alt, then press the F key?
Does that make any sense? sorry if it doesn't
TIA
