Yes, VisAD is designed for a three button mouse, but
interprets pressing any two buttons as the other (third)
button in order to accomodate a two-button mouse.

Say is right about calling visad/DisplayRenderer.getCursorStringVector()
to get the strings from the top-left corner of the screen.
You can see an example of how it is called in
visad/java3d/DisplayRendererJ3D.drawCursorStringVector().

Cheers,
Bill
