Hello Rebecca,

Are you referring to viewing alignments on the main Genome Browser 
display page (http://genome.ucsc.edu/cgi-bin/hgTracks)?  If so, the 
"reverse" button just below the main display (between the "configure" 
and "refresh" buttons) will flip the entire Genome Browser display and 
reverse complement sequence displayed when you are zoomed in to base level.

If you are instead referring to alignments that are displayed when you 
click on a track and look at a details page, there is not an option 
supplied for reverse-complementing the view there.  However, we have 
some tools that could help you generate the view you are looking for. 
If this is the case, which track are you trying to view?
