<p>A selection list is a common means of displaying and accessing data in

applications. When a selection list is displayed, the application is typically

in a permanent state, which means that the user can leave the application,

open another application, and later return to the same state. Selection lists

are displayed in the main pane.</p>

<p>Typically, the user can open items in a selection list, leading into another,

more detailed view of the item within the application. In addition to browsing

and selecting items, other functions are available in the Options menu (see <xref href="GUID-BFEEECCA-190B-4DDE-8A04-4FE918BE8690.dita">Options menu</xref>).</p>

<p>The usage of the Selection key in selection lists deserves special attention.

Depending on the case, it can do the following actions:</p>

<ul>

<li><p>Selects the item in focus. This should happen whenever it is assumed

that it is clear to the user what happens. Selecting can mean:</p><ul>

<li><p>Opening an item, such as a folder or a date in Calendar, leading to

a detailed view.</p></li>

<li><p>Executing a command when the focused item is a command.</p></li>

</ul></li>

<li><p>Opens the context sensitive Options menu. This should only happen when

the user cannot be assumed to know what happens if the Selection key is pressed.

The menu should contain only high-priority options associated with the item

in focus, not general items such as Settings, Help, or Exit. The maximum amount

of options in the context sensitive Options menu is four.</p></li>

</ul>

<p>The two types of Selection key actions should not be mixed within one list;

one or the other should happen for every item in the list.</p>
