Somewhat silly queston, but important for me

I\'m thinking about switching to CUBASE SX, no one thing that I have to know is if you are able to play the little keyboard in the piano roll edit with the mouse properly.
Cacewalk and Sonar had this ability and previous VST\'s did not. You could click on the keyboard in old VST\'s but it would make just a short \"plonk\" weather your holding the click or not?
So can you play with a mouse in SX?
