Multiple Key Press

Multiple Key Press

Multi-button press support enhances the gaming experience for the user. Multi-button
press support gives the user the ability to press two (2) keys simultaneously and the
corresponding actions of both keys will occur simultaneously. An example of this action
would be the following:

• If Left + Fire were pressed at the same time, the Java object (e.g Canvas) will

receive Left Pressed + Fire Pressed. In the same way, when the 2 keys are
released, Java object (e.g. Canvas) will receive Left Released + Fire Released.

The following sets of keys will support multi-button press support on the Motorola C381p
handset. Multi-button press within each set will be supported, while multi-button press
across these sets or with other keys will not be supported.
Set 1 – Nav (Up), Nav (Down), Nav (Right, Nav (Left)
