I just found this out and thought I'd pass this on. It's very useful when trying to read small print (especially in the early hours). If you hold
down the Ctrl key on your key board and then turn the small wheel in the middle of your mouse away from you or towards you, the print size will
change - it will either get larger or smaller - depending on which way you
turn the wheel
Try it in another place besides this board. Mine didn't work here but it did on regular internet pages.
Be sure to keep the control key down while scrolling with the middle button.
And you keep the control key down while you are scrolling the wheel? Other than that, I don't know....it shouldn't have anything to do with it being wireless.
