It does matter in two circumstances.
The more usual reason to choose shading is that highlighting (the one on the
toolbar) allows only 15 different colors, of which about half are too dark
to let you read the highlighted text unless you also change the text color
to something that contrasts with it. Shading gives you the entire gamut of
RGB colors to choose from when none of the highlighting colors will do, or
when you need more than the handful that are usable. If you do this often,
it's worth creating a macro to make shading as easy to apply as using the
highlighting button.
The other difference occurs when you're using a macro to manipulate the
document. You need completely different code to handle shading than to
handle highlighting.
