Idk. I've modified all my keybindings to closely match how I played on FFXI, to the point where the only time I have to use a mouse is to refocus windows when I try to chat. I very rarely need to use a mouse.

But what's odd is that I altered my targetting keybindings to Q and E and I cannot target other carbuncles with what I had setup. It's to the point where I want to target carby sometimes so I can actually heal it, but cant.

Not in the game now, but I can follow up post on my settings if you like.
