The bigest jump is .1 with the shift key if you need larger you will need to drag using the mouse.
You can go smaller. With no modifer you get .05 and with the option key you get .01

Once the value in the Value Slider is selected, you can scroll with either trackpad or mouse scroll wheel. Very fast (but not, obviously, using the keyboard).
