Mac OS X - Applications and File Types - Changing the system-wide default

I inadvertently changed the default application for file type .RFT ( Revisable Form Text ) from TextEdit to OpenOffice.

This was, of course, an error.

Whilst I knew how to change the default for each individual file, I couldn't work out how to change the default for all files back to TextEdit.

This blog post came to my rescue: -
