When you are doing a Search and Replace , the Replacement screen is displayed showing you the found text and how it will look if replaced. If you like what you see, clicking Replace substitutes the new text for the old text and then searches for the next occurrence. If you want to skip the displayed replacement, click the Skip button. If you are confident that the replacements are working correctly, you can click Replace All. Legacy then finds all the remaining matches and makes the replacements automatically without stopping.
