Briefly describe what each of the following commonly used options on the Replace tab specifies:  HTML Rules button, Find where, Display results in, Direction, Match case, Find whole word only, and Ignore white space differences.

What will be an ideal response?

HTML Rules button:  A complex set of conditions for searching and replacing HTML
Find where:  Where to perform the find-in all pages in the site, all open pages, selected pages, or the current page
Display results in:  Whether to show results in the Find 1 or Find 2 panel, so you can compare two sets of results
Direction:  Whether to search above the cursor's current placement in the page, below it, or both
Match case:  To find only those instances where the case matches the case of the text in the Find what text box
Find whole word only:  To ignore text found that is part of a word rather than a whole word
Ignore white space differences:  Find similar text even if the white space is different; used mostly for code and tag searches
