Keys supported by Flash Lite
In addition to the alphanumeric keys available on standard telephones, most mobile devices feature a navigation keypad, which let users navigate and select items on the device screen, and two (or more) soft keys. A device's soft keys are multifunctional keys that use the screen to identify their purpose at any moment.
A typical navigation keypad has four navigation keys (up, down, left, and right) and a select key (typically located at the center of the keypad). Different applications can use these keys in different ways. For example, a game might use the navigation keys to let the user move a character on the screen, and then use the select key to perform another action, such as make the character jump.
The following images show the most common keys on a generic keypad and on an actual device:
Not all devices and Flash Lite content types support all these keys. For example, devices that support two-way navigation don't support the left and right navigation keys (see Default navigation modes). Also, not all devices have access to the device's soft keys.
