Spacebar = Used as confirm button in main menu and used to tap mana, & place land on play area attack/defend (etc) during actual gameplay

Enter = Kind of like a "start" menu, can bring you back to title screen, muligan in the beginning of a game and save and exit changes in the option menu

A = In title menu goes to Achievments and card spoilers, while in play it brings up the current cards in yout hand in a side menu (also hides it)

Q = While in play it advances you to your next phase (Upkeep, draw, phase, you choose when each phase ends).

Im assuming that you have played magic before (so you know the rules, etc).

And the pics they are avialable on the Wagic forum
