Replace String: Enter replacement string in this field. The string you enter can be a simple replacement, a regular expression (be sure to check the 'Regular Expression' checkbox), or a replacement involving special replacement operators. To create a binary replacement using special characters, click the button to the right of this field. If you create a Binary replacement, the string, "Binary mode -->>", is displayed in the replace string field. When you are done with this field, the Search string and the Case Sensitive, Regular Expression and Match Whole Word settings, click "Apply" to save the information to your script. Special Replacement Operators are valid in script replacements strings.
Note that in the current example, the highlighted line in the Search/Replace list makes use of Regular Expression replacement using the %1 operator to include the search results yielded by the * search operator (see the Search String) in the replacements.
