Center the middle of a word page

An idea:

Go to the text area (by View/Header and Footer), scroll down to the center of your page, and with the line tool, draw a line that goes from one margin to the other at the center of your page. Return to your page.

To calculate the center, place the vertical ruler. Optionally, open a new file with the same margins as the one you are working on and go to Layout Page Setup/Center. Your cursor will position itself at the center; note the corresponding cm.
Return to your file and follow the procedure I wrote at the beginning.

You will have this on all your pages. If you only want a few pages like this, you need to create a section.
