Use the tab panel to select the resource you are interested in.

Navigate -- Next Resource or
Navigate -- Previous Resource
to view the next or previous resource of the same type, as written inthe IFF file. Resources are not necessarily found in any particularorder within the IFF file, so it may be easier to navigate a complexset of resources via the
