Multimedia keyboard

This article is a stub. You can help Deskthority by expanding it.

A multimedia keyboard is one with media keys — additional buttons, typically along the top, for controlling audio playback, for starting common applications (e.g. e-mail client and Web browser) and other auxiliary functionality.

Many such keyboards also contain a volume knob, implemented as a rotary encoder so as to be able to provide relative volume changes regardless of the volume level set by the user in the operating system and application software (otherwise, the knob would need to be motorised and under computer control).
