Hello Bob,
Depending of your N++ installation, the shortcuts.xml file, which contains a Macros section, should be located :
in the %AppData%\Roaming\Notepad++ folder, if you used the installer ( the npp.x.x.x.Installer.exe file )
in the same folder than you copy the Notepad++.exe file, if you used a ZIP or 7Z archive ( the npp.x.x.x.bin.zip or npp.x.x.x.bin.7z files )
Cheers,
