Word 2013 doesn't have a menu (unless you call Home, Insert, Page Layout, etc., a menu), and you can't customize what's not there. Word does still have context-sensitive right-click menus. However, unlike in previous versions of Word, the user interface no longer provides a way to customize them.
If you have any questions or suggestions, please feel free to ask OfficeToolTips team.
As you work on a document, you normally see the results of the field codes that you've inserted instead of
the actual codes themselves. Because of this, these field results may be difficult to distinguish from
normal text, so Word has added a feature called shading that helps you to locate such results.
Including a large number of in-line pictures in your documents slows down Word's performance. You can
improve performance by replacing actual pictures with picture placeholders.
