+presses</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>A key press is a press and release of a key (down and up).</p>
+<p>Typically, the primary action of the key is performed when the key is pressed
+down, already before the key is released (there may be exceptions to this
+rule; see <xref href="GUID-26435FE1-D912-4AA2-96EE-82B35DA231E6.dita">Typical functions
+of the standard keys</xref> for an example).</p>
+<p>Some functions depend on the length of the key press:</p>
+<ul>
+<li><p>In a short press, the key is held down for less than 0.6 seconds (please
+note that this time-out value may depend on the product implementation). If
+the key is held down longer, the result is a long key press.</p></li>
+<li><p>If the pressed key (in the given context) has functions for both a
+short and long press, the short key press action is performed first at the
+moment when the key is pressed down. If the key press is long, then the long
+key press action is performed. In the case of the Home / Menu key and the
+Edit key, the interaction is different, causing the action on the key release
+event. </p></li>
+<li><p>Certain keys, possibly in certain contexts only, may perform key repeat.
+Key repeat starts after the long key press time-out when the key is continuously
+being held down, and the associated function is performed according to the
+key repeat frequency. For example, in scrolling within lists and text editors,
+these frequencies are by default 6 times/second for vertical and 10 times/second
+for horizontal scrolling (the repeat frequency may be product or application
+specific). </p></li>
+<li><p>Long key press actions and key repeat actions are not defined at the
+same time; only one can occur in the given context. </p></li>
+<li><p>The primary key press action should not be conflicting with the long
+key press action or key repeat action.</p></li>
+</ul>
+<note> With certain input hardware (for example, Roller), long
+key presses and key repeat may not be possible. The long key press actions
+and key repeat actions should be designed so that this does not cause harm:
+the long key press must never be the only way to perform a function</note>
