The nunchuck has shoulder buttons just like the ps3 controller . That is what I use . However the sixaxis can be set to do functions also but not used it myself so not sure . . .
Forgot to answer about what I put the mouse on . I either pull up a table or put it on a telephone directory with mousemat on top .

There is also a wireless version from a different developer which has been regarded highly ,
