Yes. These functions are called when you press each key:
servercmdShiftBrick(client,x,y,z)
0,1,0 = Shift forwards (Numpad 8)
0,-1,0 = Shift backwards (2)
1,0,0 = Shift right (6)
-1,0,0 = Shift left (4)
0,0,3 = Shift up (+)
0,0,-3 = Shift down (5)
0,0,1 = Shift up 1/3 (3)
0,0,-1 = Shift down 1/3 (1)
servercmdSuperShiftBrick(client,x,y,z)
servercmdPlantBrick(client) (Enter)
servercmdRotateBrick(client,direction) (9 and 3) <- I'm not sure whether this one is the function
