Feature request: Have control-click act as right-click, to better support Macs with one-button mice.

There are two controls that use click and right-click to increase and decrease a number, namely sfx speed and music pattern selector. Macs usually come with one-button mice or trackpads, so right-click actions are often also available as control-click (hold Control, click). In 0.1.0 control-click acts as "fast increase" instead of "decrease." It'd be great if control-click were "decrease" in these cases.

I notice shift-click is also "fast increase," so there's no loss of a feature. Shift-control-click could be "fast decrease."

Thanks!
