Which feature will mark all formatting changes made to a document?

You can see who has been making changes in a document by turning on the track changes feature. When this feature is turned on, MS word will mark up new changes made to the document. Click on the review tab, tracking group and then select the track changes. 

If you would like to accept all formatting changes but not text, you will follow the same procedure and on the track changes option, you will click on show markup and then turn off all check marks apart from the formatting check mark.

a macro is a tool that allows you to automate tasks and add functionality to your forms, reports, and controls. for example, if you add a command button to a form, you associate the button's onclick event to a macro, and the macro contains the commands that you want the button to perform each time it is clicked.
