Many people know, but a lot don't that you can get to a function on your phone quickly by just memorizing the shortcut to that function. The numbers to these shortcuts tends to change with the model of the phone. As an example on a 3390 if you press menu/4-1 that will bring you directly to the normal profile. Menu/4-2 will immediately bring you to the silent profile. Menu/1-1 will do a phone book search. Menu/2-3 will give you the message writing screen.
