If you find a long text in all caps where a couple of steps are justified,
Copy and paste into Word.
Highlight the whole thing.
Hit Shift+F3 once or twice to toggle through all caps, initial caps, all lower case.
Fix the caps you need from the all lower case, and paste back.
Some years ago a "friend(?)" of LiK sent her a manuscript that was "due at the printer in three days and he was late." He had typed all 570 pages ALL IN CAPS in the belief that it would be "easier to read by his reviewers."
With two computers and two people working long shifts, we got it to the printer, converted and mostly proofed. We've heard that it's been a best seller (in a small market). It's still listed as available at Hazelden Publishing, a dozen years later.
I'm not sure whether she still considers him all that much of a friend.
