Edit key Power key
The navigation keys can be ordinary buttons, or they can be implemented using different control devices, for example a roller which can be rotated and pressed so that up, down and select functions would be mapped to it.
Hardware solution may have some effect on the navigation functionality: for example a long key press event can't be accomplished with a rotating device.
Each softkey has a corresponding textual label on the bottom of the screen.
The Edit key is the only key that can be used simultaneously with another key press, for example, the combinations where any of the navigation keys are pressed while the Edit key is held down.
See section Keypad functions in chapter Interaction style for more information about the usage of keys.
Extra keys
Other specific keys can be added to a product to emphasize or facilitate some functions. These extra keys could be used to control applications or hardware such as spoken commands, sound recording, and audio volume control.
