According to the LyX wiki and other sources I can use \renamecommand{\abstractname}{Summary} without an \addto if I remove (or deactivate) the babel package.The document class is KOMA-script Report.
Reading the KOMA-script document I see why the above does not work, but I don't see how to change the name of the abstract _environment_ (not a command) to summary. If that's in the LyX Wiki I missed seeing it. Rich
