<concept id="GUID-2131E679-779D-427D-BD41-47D9949A8749" xml:lang="en"><title>Disabling

hardware key shortcuts</title><shortdesc>This document describes how to disable hardware key shortcuts when

none of the items in a list are highlighted.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>If an application has item-specific hardware key shortcuts, they must be

disabled when there are no visible highlights in lists.</p>

<ul>

<li><p>Applications must retrieve the list highlighted state using the <xref href="GUID-019B2B8B-AFAA-3806-B796-3D91B4D79361.dita#GUID-019B2B8B-AFAA-3806-B796-3D91B4D79361/GUID-951D2BAE-C567-362C-9F55-5C3969144F89"><apiname>CEikMenuBar::ItemSpecificCommandsEnabled()</apiname></xref> function.

The function returns <codeph>ETrue</codeph> when item-specific commands are

enabled in the menu bar (that is, a list has highlighted options) and <codeph>EFalse</codeph> when

they are disabled (the list does not have highlighted options). </p><note>Symbian^3

supports focused items on hybrid devices when the UI is manipulated through

key events. For details, see <xref href="GUID-28A0E021-C702-4AAF-9C64-B60B09B40176.dita#GUID-28A0E021-C702-4AAF-9C64-B60B09B40176/GUID-D556C1B0-9D9A-4219-BFF8-5CDBA10677CA">Moving

in hybrid devices</xref></note><p>For example, considering that an application

supports single-tap, the following code enables the delete action only if

the call to <codeph>ItemSpecificCommandsEnabled</codeph> indicates that an

item is currently focused. </p><codeblock xml:space="preserve">TBool CLogsRecentListView::ProcessKeyEventL(
