Many Word features can be hard to find unless you already know where to look. For example, to edit or insert a page header or footer, you need to open the Insert tab on the Ribbon, which is not even remotely intuitive. Instead, click on the search bar at the top of the window and type Header. Word will show a menu of header-related features and you can choose the one you want. Unfortunately, Word won’t show you where to find those features on the Ribbon, so you may need to use the search bar again.
In Windows, the keyboard shortcut that gets you to the search bar without using the mouse is Alt-Q, which you can learn by hovering over the search bar with the mouse. On a Mac, the search bar is the field in the menu bar that says “Tell me.” The only keyboard-friendly way I could find to reach it was to press Cmd-F6 until the keyboard focus moved to the menu bar, tab right until I reached the search bar, and then press the space bar.
