<p>When designing a Symbian application, the UI must be designed so

that all tasks can be performed with touch. Therefore, the design

must not rely on hardware keys (except for turning the power ON and

OFF).  </p>

<p>The touch UI in the Symbian platform involves various specific

touch components, component and UI behavior changes, layout changes

and additions to the <xref
