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

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

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

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

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

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

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

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

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

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

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

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

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

    27 sibling folders. For navigating hierarchical application structures, the basic

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

    29 <ul>

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

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

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

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

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

    35 </ul>
