I managed to map my function keys f1,f2... but I can't seem to map backspace and right click. I tried using codes #2 and #8 but it's not working out. Am I using the correct codes?

Alt Tab is not working for me at all. Not sure what I did wrong.

After using Ctrl + G to release my cursor out of game, once I go back to the game I can't move up and down. I can move left and right but the aim is not working.
