The FlyingFader will accept keyboard values and fade to them over 1.5
The FlyingFader will accept keyboard values and fade to them over 1.5
seconds. Combinations of control and alt change that speed. RMB
also creates a fade and LMB will cancel them. Colors are pretty
and informative. Fades can be created manually with the newfade()
function.
