Well, sorry for being such a newbie. All I want to do is put in the Growl log which window was just changed to. Logging the window number alone is sufficient, but the window name would be better. Have I missed some TotalSpaces preference? Is this possible through the TotalSpaces Ruby api? If not and not, is my only option to request that the feature be added to a future release of TotalSpaces? Thanks, Bob
Never mind! 
I followed the trail of breadcrumbs starting at http://binaryage.github.io/totalspaces-api/ruby/rdoc/README_rdoc.html and now am not such a newbie. Thanks to all who left breadcrumbs.
Ok, good you found what you needed.
