A couple of weeks ago I attended a talk by New York Times writer David Pogue. He was talking about good vs bad user interface design. Apparently he wrote a column once that complained that to put his Nokia phone into silent mode you had to go down into about the 4th level menu. He received a letter from a Nokia engineer who pointed out that to switch your phone to one of you profiles you just have to tap the power button. It is an undocumented feature. Sure enough, I have had Nokia phones for years and did not know that either. Here is further information from the Nokia Tips site:
As you already know, you can change profiles by selecting them using the Profiles menu option. You may also know that you press the power button and then select the profile you want from the resulting menu. However, you may not have known that you can select a profile even quicker than that. Just press the power button once, then hit key 2, 3, 4, 5, or 6 (or 7 for the 3390). This will select the various profiles immediately. Power-2 is “Normal” and so on up the list. Power-1 turns the phone off instantly (no waiting).

I use the voice commands on my Nokia to change the profile since I can do this without looking at the phone. When using the headset, it is the only way to avoid having to remove the phone from its holder.
