Re File Renaming.
Aduke.
I cannot find a winning combination. Maybe there is a combination I have not tried yet.
For example, File Name plus Custom Text will retain "Edit",HDR" etc in the original file name bit, which I want to avoid in some situations.
Also, I may have created long filenames when working with Ps, that I want to shorten if sending to a client.
If I use just custom text I have to re-write the full filename, but I do want to retain the original stub and have to remember it and then retype it. What is worse, it remembers the text from the last time I used it and there is a danger of apply this old text to the filename.

Brilliant... why did I not think of that sooner.
Getting back to the main point.
Lack Of Development focused on features for existing users.
F2 is the keyboard shortcut for changing the filename. Surely the optimum would be to use F2 and allow me edit manually the existing filename and then (if it suits better) to apply a formula.
In the meantime JJJ's suggestion will work a treat. Thanks to JJJ and Aduke.
Now, if the other ten items in my list had an easy fix.
