Execute the following command to add custom appointment types.

<pre>
Defaults write NSGlobalDomain SkyScheduler_customAppointmentTypes \
'({icon="myApptypeIcon.gif";label="my appointment type";type="my_apptype"})'
</pre>

The file <tt>'<instPath>/.libFoundation/Defaults/NSGlobalDomain.plist'</tt> also can be edited directly: 

<pre>
    "SkyScheduler_customAppointmentTypes" = (
        {
            icon = "myApptypeIcon.gif";
            label = "my appointment type";
            type = "my_apptype";
        }
    );
</pre>

The <tt>'myApptypeIcon.gif'</tt> must be present in the WebServerResources:

<pre>
'<instPath>/WebServerResources/English.lproj/'
</pre>
