Touching this button results in a touch -with bit 4 of the first byte set, while only the lower 4 bits (0-3) are -used to indicate the number of touches. - -Report a KEY_LEFTMETA press when this happens. - -Note that the hardware might support more than one button, in which -case the "id" byte of coor_data would identify the button in question. -This is not implemented as we don't have access to hardware with -multiple buttons. - -Signed-off-by: Sergei A.
