<DD>This callback is the prefererred way for handling the "fire" key (center softbutton)
 in order to allow 3 button devices to work properly. When overriding this method
 you should also override isSelectableInteraction to indicate that a command is placed
 appropriately on top of the fire key for 3 soft button phones.
