<para>The channel editor dialog shows three sections. At the top the frequency table and related options. In the middle the channel list. At the bottom you can edit individual channel list entries.</para>
<sect2 id="zapping-ce-populate">
<title>Populating the Channel List</title>
<para>First you must choose the frequency table used in your country. To do this, select a country from the drop-down menu in the top left corner of the dialog. Then you can:</para>
<itemizedlist>
<listitem>
<para>Click on <guilabel>Automatic station search</guilabel></para>
<para>If this is supported by your TV card Zapping will scan
all RF channels in the frequency table and enter the found stations in
the channel list. When VBI decoding has been enabled in the
preferences it will also try to determine the station names.</para>
</listitem>
<listitem>
<para>Click on <guilabel>Add all channels</guilabel></para>
<para>This will add all RF channels in the frequency table to the channel list.</para>
</listitem>
<listitem>
<para>Click on <guilabel>Import XawTV configuration</guilabel></para>
<para>This will import the channel list from the XawTV
configuration file, if you used the XawTV application before.</para>
</listitem>
<listitem>
<para>Naturally you can also enter channels one by one
yourself.</para>
</listitem>
</itemizedlist>
<para>Now you can edit channel names or reorder channels on the list. When you are satisfied click on <guibutton>OK</guibutton> to store your changes and leave the dialog.</para>
</sect2>
<sect2 id="zapping-ce-editing">

<sect3 id="zapping-ce-add-remove">
<title>Adding and Removing Channels</title>
<para>To add a new channel, click on the <guibutton>Add</guibutton> button. To insert a channel at a particular position, select the respective row first.</para>
<para>New channels are empty and will not show in menus. You can leave it this way to create a gap in the list. That is useful when you switch channels by entering the number in the list.</para>
<para>To remove one or more channels, select the rows and click on the <guibutton>Remove</guibutton> button.</para>
</sect3>
<sect3 id="zapping-ce-reorder">

<variablelist>
<varlistentry>
<term><guilabel>Name</guilabel></term>
<listitem>
<para>The name you want to give the channel.</para>
</listitem>

</varlistentry>
<varlistentry>
