+<context id="GUID-F94E9859-C7AE-45FA-80DC-F62625C32EA4"> <p>If an application
+handles the list targeted MSK or Enter Key events (<codeph>EKeyOK</codeph> and <codeph>EKeyEnter</codeph>),
+for example, in the <codeph>ProcessKeyEventL()</codeph> function, the handling
+of these key events must be moved to the listbox observer function <codeph>HandleListBoxEventL()</codeph>.
+The MSK or Enter Key event related action must be performed when an <codeph>EEventEnterKeyPressed</codeph> event
+is received. This way the list item-specific action is performed on a key
+event only when there is an option highlighted in the list.</p> </context>
+<example><ul>
+<li><p>Remove key event handling code from <codeph>ProcessKeyEventL</codeph>.</p><codeblock xml:space="preserve">TBool CLogsDetailView::ProcessKeyEventL(
