<para>
The purpose of the Observing List Tool is to provide convenient
access to some common functions for a list of objects chosen by
you. Objects are added to the list by using the <quote>Add to
List</quote> action in the <link linkend="popup-menu">popup
menu</link>, or by simply pressing the <keycap>O</keycap> key
to add the currently-selected object.
</para>
<para>
Objects in the list can be sorted by any of the data columns
(Name, Right Ascension, Declination, Magnitude, and Type).
To perform an action on an object, highlight it in the list,
and then press one of the Action buttons at the top of the
window. Some actions can be performed while multiple objects
are selected; others only operate when one object is selected.
The available actions are:
<variablelist>
<varlistentry>
<term>Center</term>
<listitem>
<para>
Center the display on the selected object, and begin Tracking
it.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Scope</term>
<listitem>
<para>
Point your <link linkend="indi">telescope</link> at the
selected object.
</para>
</listitem>
</varlistentry>

<note>
<para>
The Observing List tool is a new feature and is still under
development. We are planning to add more features, such as
adding objects to the list by selecting a region in the sky, and
the ability to save observing lists to disk.
