It seems not only me who don’t like the sound of multimedia key. Some of the latest S60 phones add a new key, called Multimedia key, which is used to display additional shortcuts on the screen. By default, if you press they key, it produces sound.
We can disable this sound by pressing Multimedia key and then select Configure menu. At the end of the settings, there is Sounds option. If we change this to output, pressing Multimedia key will not produce any sound.
Compatible devices: s60 3rd Edition, Nokia Nseries.
