Now that I finally found that you can scrub the value of a input with side-to-side scrubbing on the mac, I think it would be awesome to add key modifiers to adjust increments.
For example, common key modifiers are: no modifer increments to the nearest whole number. (or perhaps the default increment of the input) option key increment by adding or subtracting one to the current value command key increments by .1 and shift key increments by 10
