The symbol bar where the word interface inserts punctuation directly is missing

The normal interface, as shown in the following illustration, appears below the Drawing toolbar.

If it doesn't show up, you go to these places to find it. View → toolbar → symbol bar. Like the following figure.

What if you can't find the symbol bar in the menu above? Click on the "Customize" menu above to pop up the dialog box below.

In the diagram above, find the last symbol bar in the Toolbars list, and check the front of it to resolve the problem.

Note that if you do not find the words "symbol bar" in the image above, your Word version is compact, without this feature, you can download a full version down, reinstall, select "full" installation to have this function.
