Final answer:

Step-by-step explanation:
To access the header and footer tools in a Word document, you should open the header or footer. This can typically be done by double-clicking near the top or bottom of a page in your Word document. Once you do this, the header and footer tools will appear, giving you various options to edit them. If you want to accept or reject changes in a Word document, you would click the Review tab above the tools ribbon. When reviewing a document, toggle Track Changes to off to make sure that changes you make aren't tracked as edits. To see all changes, use the Reviewing Pane in the Review tab, and to navigate to a specific revision, click on the revision within this panel.
When you are ready to accept or reject revisions, use the Accept and Reject options in the Review tab. There are options to accept or reject a single change or all changes at once. But remember to review each change individually to avoid mistakes. After finishing the review process and making sure that all edits are completed and no comments are left, remember to save your changes. This step ensures that your document reflects all the final edits and is ready for distribution or submission.
