I'm playing on a Dell laptop where I have to press Fn+Insert which definitely would be a pain. Luckily I have a Cyborg Mouse, whose software is pretty good allowing me to bind one of the extra button to the Pause key.

Rebinding some of the other keys would definitely have been useful. Yeah I though so, hope it stays in because combat was no fun to me until I figured this out.

On my one the pause key is Fn+Insert. It seems to throw out a different key code than when I press the Pause button via the On Screen Keyboard in Windows.

I tried initially with Autohotkey but that didn't work, the game recognised all other keys but Pause wouldn't work, I think the pause key code is somehow tied to Numlock on my keyboard as well. In the end, my Cyborg mouse utility was the only thing that will work. I don't know if it is related to the game or the computer, because the game did recognise other Autohotkey rebindings, just not Pause.

As for rebinding the in game keys, I couldn't find a way to do that, I would have liked to have quicksave as F5 instead of F6.

Let us know if you figure it out.
