<concept id="GUID-ACF69260-D643-4709-8DAB-33FD92940F86" xml:lang="en"><title>Hierarchical

application structures</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>When browsing within a hierarchical application structure, the Symbian

user interface offers direct access from one folder to another (sibling) folder

in the same level. The Arrow left and Arrow right keys are used to accomplish

this. The Navi pane displays the sibling folders as tabs.</p>

<fig id="GUID-A99BF5A7-9D80-4CBA-A078-5992079E6728">

<title>In this example, each displayed state is a folder containing a list

of items. State 1 contains three folders (1-1, 1-2, 1-3). When the user has

opened one of these, there is a possibility to move directly into the other

two folders without first going back to state 1. Folder 1-1 contains two sub-folders

and folder 1-2 contains one.</title>

<p>This additional navigation feature can be interpreted as a shortcut between

sibling folders. For navigating hierarchical application structures, the basic

navigation rules are applied, noticing the following:</p>

<ul>

<li><p>Moving from one folder to another has no effect on the function of

the Back softkey in these views: from all of them, the Back function leads

to the previous hierarchy level. </p></li>

<li><p>The navigation shortcuts can only be applied when there is no other

use for the Arrow left and Arrow right keys in the state.</p></li>

</ul>
