Spells changing levels?

[Gatts]

I would agree that the buttons for level 1,2 could be there... as sometimes I just sit back in my chair, away from keyboard and only with my trackball on my knee or chair armrest. - But as many games need keys (most I play) I just attach the keyboard keys to my old gamepad - which I can hold in my left hand (keyboard is too huge to have it on my lap... and there is my girlfriend anyway)... so I have way for using ctrl, alt w/o keyboard,.... just in general I wonder that these buttons are not there (new generation players are used to unwritten rule - no button = no function... not like old games where you had 3 page manual only about keys )
