<p>In case the hardware has no dedicated volume keys, the audio volume is+
−
adjusted using the Arrow up and Arrow down keys. When the user is controlling+
−
the volume, the key event brings the Volume Control pop-up to the view, and+
−
the pop-up disappears after a time-out when the user has done the adjustment.</p>+
−
<p>The application may need up/down key events for controlling some other+
−
component, such as list. In this case it needs to be decided whether that+
−
view can be left without Volume Control or whether the Volume Control component+
−
is accessed via the Options menu or toolbar.</p>+
−
<p>Volume is adjusted with touch by dragging the slider handle and audio can+
−
be muted by tapping the icon in the UI component, refer to <xref href="GUID-BB8B3A11-0BBC-4759-A7F4-A28C9E70573F.dita">Touch+
−
support for common UI components</xref>.</p>+
−
<p>The Volume Control UI component may also be always available in the view.+
−
In this case it is fixed in the layout.</p>+
