We are using LabView to control an electron gun power supply. We need to view the spot on a phosphor screen while operating the controls. It is very difficult to keep the mouse on the up/down arrows, when not looking at the front panel. It would be nice if we didn't need to point the mouse at anything in particular, rather could move it right/left or up/down. Ideally, we'd click on the parameter to be controlled, then have it start at the current value with mouse movements changing the value about that starting point.

Tom, The button in the center is a good idea. It looks like mouse tracking will be an option for us. Thanks for your help.
