Yes, this is exactly what I was describing in my message!

So my question is this... what's the best way to apply a new shading color to the whole selection?

I was thinking of something like this:

1) select all the paragraphs you need to shade;
2) apply the new shading to the whole;
3) loop through each word inside the selection;
4) check which word has a different shading than the one you just applied at step 2, and then reapply the shading to that specific word.

What do you think? Is there a faster, more elegant way to do it?
