Replace Text Options
This group of options defines the comparison method that the Editor uses when makes a search and a replacement.
Case Sensitive
When the Case Sensitive option is checked, the Editor differentiates upper from lower case characters when performing a search.
Whole Words Only
When the Whole Words Only option is checked, the Editor searches for words only; that is, the symbols matching the search string must have punctuation or space characters on both sides.
Prompt on Replace
If you checked Prompt on replace option and if you chose Change All. Then when the Editor finds the specified text, it asks if you wish to make the replacement for every instance of the search text.
You can answer 'Yes', 'No, 'All' or 'Cancel'. 'All' means that all remaining replacements will be done without further prompting. 'Cancel' aborts the search.
