Abstract
Mobile telephone handset navigation functions are integrated into certain of the alphanumeric keys of the mobile keypad. Up, down, right, and left navigation functions are integrated into four alphanumeric keys. The mobile automatically toggles between the navigation and alphanumeric functions of these keys based on where the user is within the interface routine of the mobile. Optionally the user can manually toggle between the navigation and alphanumeric functions by pressing a menu key.
