In general you shouldn't have that problem with XyWWWeb routines, because our practice -- which is
also the best practice -- is to test for key code or scan code (VA$KC or VA$SC) rather than key
output. As for your own code, if you're going to modify it, why do something Rube Goldberg-esque
like switch KBD files when a simple additional test for $KC will do. For example,
=="{CrLf}">...
becomes
=="{CrLf}"!==28!==104>...
