Hi,
glad to hear u like it! But i'd rather not occupy more keys because the ones you mentioned are already partially used by the game.

yeah i thought about that, thanks for the answer & see u soon on the server ;p

And for the people like me, i found something useful, Auto Hotkey so u can remap the key like u want ;)

Better not everyone knows that f10 is the "ingame costumization menu" :P

On topic why not changing or allowing the use of both like f1 and HOME bottom

I don't know if there is a keybinding for the home button in udk.

Lol Deep ^^ there is always a solution, for me i put F10 for skeleton ability, F11 for potion and F12 to teleport with the software (because i play with the arrow). With it i can tell to my keyboard that when i tip F10, it understand F5 ^^ very useful i used this for several game like Killing Floor 2 or Fallout 4 ;)

F11::F4
