I cannot seem to control the volume on my laptop unless I do it the long way (hidden icons + speakers + adjust volume). I should be able to access a "hot key" of some sort, but I cannot locate one. It looks as if I should be able to hit the Fn + 4 key. However, the Fn key only serves to bring up the keys operated with F1 - F9. I hope y'all can understand what it is I am trying to say! Thanks!
