Thanks for the suggestions. It's not always obvious what element I want to 
highlight, though, beyond "everything that ends up on the same line. It may be 
that the thing I want to draw the attention of the user to is in a paragraph; 
in that case, I highlight the full paragrahp. Or it may be in a title; in that 
case, I highlight the full title. Or it may be part of a list; in that case I 
only highlight the item that contains it.

When the text that shr inserts isn't wrapped, I just need to highlight the line 
that contains that text after rendering is complete. When it is wrapped, 
however, it becomes unclear what exactly to highlight.
