In the replace dialog box, clicking what button changes highlighted text

In the Replace dialog box, clicking on either “replace” or “replace all” button will change the highlighted text and replace it with the new text you have specified in the “replace with” text field. The highlighted text is a result of finding a specific word and the dialog box gives you the option to replace the found word with a new text. It is more appropriately referred to as the “Find and Replace dialog box.”
