I had the idea to bring the items up inside an info box with a numbered line to represent for each search item as well as each replace item. And, next, up comes a wizard with only those (representative) numbers in it of which you choose a number.
In that way, the code (chars with special meaning) itself thus is not to be displayed inside a wizard. (not that it can't be done with NTB but it does become more challenging to do so)
But I like Harvey's approach even better - that is, to just show it in a doc.
Since I'm lazy, (just click on a line instead of select an item) I might be tempted to add Select LINE to Harvey's
