    13 and basic softkey configuration</title><prolog><metadata><keywords/></metadata></prolog><conbody>
       
    14 <p>The Symbian platform supports two softkeys and labels the Selection key
       
    15 in the middle of the Control pane. This, in effect, looks like a "middle softkey".
       
    16 Touch UI does not have the middle softkey label visible, refer to <xref href="GUID-BB8B3A11-0BBC-4759-A7F4-A28C9E70573F.dita">Touch
       
    17 support for common UI components</xref>. The softkey labels are placed in
       
    18 the control pane (the bottom area of the screen). The left and right softkeys
       
    19 always have textual labels, but the Selection key can also have two icons
       
    20 in certain situations.</p>
       
    21 <p>The three softkey configurations supported in the Symbian UI style are
       
    22 the following:</p>
       
    23 <ul>
       
    24 <li><p>Basic Symbian portrait-oriented UI with softkeys immediately below
       
    25 the screen (the middle softkey label is visible) </p></li>
       
    26 <li><p>Symbian UI with side softkeys in landscape (both left and right rotation
       
    27 possible, middle softkey label not possible) </p></li>
       
    28 <li><p>Symbian UI with bottom softkeys in landscape (middle softkey label
       
    29 not possible). Not available for Touch UI.</p></li>
       
    30 </ul>
