If you already have my Fast Formatting Fixes Guide, you've seen one of the "nuclear options" that I recommend clear all formatting is CTRL-SHIFT-N. I describe it as returning the selected text to Normal formatting (according to whatever the Normal Style for your document is). After all, that's what Microsoft says that command does.
However, some of you tell me it doesn't quite clear all formatting. In fact, it seems to work a bit randomly. In this tutorial, I'm going to show you why that is. I'll also show you how you can use CTRL-SHIFT-N in particular situations and a different command to substitute.
