Respuesta :
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.”
ANSWER: Replace Button
EXPLANATION: After opening the replace dialog box and putting the desired values in the boxes, we need to click the 'Replace' button to change the highlighted text. If the word which needs to be changed appear multiple times in the document, then clicking on 'Replace All' is advised as it would change all the old words with the new ones.
