I just wrote this function to make a backup of the current file, but I'm not happy with the solution I used: I have this second write-file to return to the original file. Is there a better (probably also faster) way? Thanks in advance, weber (defun make-manual-backup () "Save a copy without changing to new filename. Useful for making a copy of working file in development."
