Use of the mouse
Use the left mouse button for Black,
the middle for White,
the right hand one for correction.
On a Mac (with only a single mouse button)
one can press the Alt or Apple key simultaneously
to get middle and right button, respectively.
People tell me that under Windows with a two-button mouse
one can use Alt-RightButton for White.
