You can interact with the features on your phone in several ways: 

Soft Keys

Soft Keys located below the screen, give you access to the function displayed on the screen above the soft key. The soft keys change depending on what you are doing at the time. The "More ..." soft key shows you that more functions are available. 

Feature and line buttons

located on either side of the screen, give you access to phone features and phone lines.
