In Microsoft Word 2008 for Mac OS X, if you open a “Find” dialog, and if it has focus, it will capture cmd-S (the universal “Save” command) and cause it to toggle the “sounds like” option in advanced find options. It will sort of capture cmd-W (the universal “close Window,” which will close the Find dialog). It will not capture cmd-Q (the universal “Quit”), which will quit the program and close all its windows, assuming your document has been saved.
Which you thought you’d been doing by hitting cmd-S. And then you wonder why your search results were so weird.
Thanks again, Mac BU!
