What is the fastest way to turn the phone into silent mode? The title kinda tells it all. Sometimes I need to turn silent for a meeting and the procedure is like:


Unlock the phone
Click on Menu
Go to Settings
Click on Sound
Enable Silent mode


Apart from (1), which can't be shortened (can it?), I want to minimize the remaining 4 clicks.

EDIT: I have a Nexus S, but I'm more interested in things that are not specific to models. Also, please feel free to add model-specific answers, as other people may find it useful.
Personally, I think that the easiest way (apart from sliding right to left, but that's not available on all phones) to put the phone into silent mode is to hold down the power button for a short period of time, then select Silent mode.
