Definitions for "Scrollers"
Scrollers automatically appear whenever you create or drag anything into a VDACC that is larger than its visible perimeter area. Unlike conventional scroller bars, NBOR scrollers are visually transparent but are solid to the touch. In addition, by holding down the Shift key and clicking on any VDACC scroller, you can turn this scroller into a vernier control. This means that the scroller will have ten times more resolution, but it will therefore scroll the VDACC by 1/10th of its height width. See Scroller Markers.
