delete a keyword from a subset of files without deleting it from all files to which it is assigned?
1. Query up the files that have the keyword. 2. Select those from which you want to delete the keyword. 3. Use Edit | Invert Selection to select all the ones where you want to keep it. 4. Assign a new keyword with some arbitrary value to those files. 5. Use File | Database | Edit Keywords to delete the first keyword from all files. 6. Use File | Database | Edit Keywords to change the new keyword to be the same as the one you just deleted.
