I've created a modified Standard Letter. The modifications include some deletions. I want to review the original Standard Letter. How can I do this without replacing my modifiec letter?

Options I would consider:

1. Save modified letter in _____, restore original standard letter, view modified standard letter in ____, restore modified standard letter (cut/paste from ___)

2. Find where PS saves copy of original standard letter and open with ___ for review.

"____" could be Word, Wordpad, Notebook; I don't know what would work, do you?

I am not wedded to the above, something simple that works would be fine.
