This is important for people who's phones are password protected. Because pressing mute puts it into standby, which is not password protected.
Don't forget this can differ according to your region, azerty vs qwerty users.
1. Toggle between vibrate and normal profiles
Hold "A" on azerty phones
Hold "Q" on qwerty phones
2. Lock the keyboard
Hold "Q" on azerty phones
Hold "A" on qwerty phones
Some people may not get it therefore the clarification.
