The view Next span will normally be greyed out. Only
if the user enters a search term in the Map Range Box
(text input at upper left) that returns more than one
value. For example:
1 - Load Homo Sapiens
2 - Load the refseq track
3 - select chr1, then Load Data
4 - do the same for chr10 and chr21
5 - in the Map Range Box, enter "ADAR" and hit enter
It should zoom, and the status bar should say "found 3 spans"
Now, try the View -> Next Search Span
It should zoom and the status bar should say "zoom to span 2 of 3"
You can do it again, and it will say "Zoom to span 3 of 3"
and the menu item will be greyed out now, because there are no
more spans.
