Yes, the ability to use the number keys instead of the function keys has been purposefully added to the game for those who cannot easily access the function keys.
not all of my keys work. for gams, i rely on bing able to change my key bins. i can sort of skirt by on just going to the menu when i want to check truth bullets an sav, but for class trials, i can't get pass the prologue b/c i can't get the motional truth bullet. will this b implement any time soon? :(
