+down and hold</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>Touch down and hold is used, for example, to open the Symbian
+stylus pop-up menu. Applications can use an animation (starts after 0.15 seconds
+from the start of a stylus down event) to indicate that a Touch down and hold
+action has been initiated.</p>
+<p>On the whole, Touch down and hold may be difficult for users to find, and
+therefore its use should be considered carefully. As in the case of task swapping,
+the use of Touch down and hold should aim at being analogous to using a long
+key press on the hardware keys.</p>
