What OP wants is what many of us used to play in FFXI. Hoping they implement it. But me personaly have converted to joypad (also played with pad in my last year of FFXI) thanks to not so fun tendonindits. (no i didnt get it from keyboard. But keyboard isnt giving my arms rest when that is needed.. Working 10 hours a day at cpmuter, so when home its joy time

But hope SE will make it possible to use keyboard like in ffxi.
