You can attach up to three functions at a time to My own key. Choose the three that you use most often from: make a call, listen to the current time, listen to a new text message, mute/unmute, and reject a call with a predefined text message.
To use My own key, you will need to have the Accessory Setup Application (ACA) on your device. Some Nokia devices come preloaded with the application and for others it's easily downloadable from the Nokia website.
