Using wildcards in the "Find What" box to find "Rule ##" was easy but apparently, they can't be used in the "Replace With" box.

What I'm trying to do is replace this format:

RULE 45
Some Text Could Be One To Several Words Long

to

RULE 45 - Some Text Could Be One To Several Words Long

My purpose here is to have a cleaner table of contents. Using the latter format with style, the resulting ToC would look like:

RULE 45................................................ ......................52
Some Text Could Be One To Several Words Long.................52

Whereas the latter format would result in something cleaner:

RULE 45 - Some Text Could Be One To Several Words Long...52
