Thinking about it, if you literally just want to repeat content, you can of course make use of headers in Word. Usually, headers (or footers) are for page numbers, obviously, but you can anchor a graphic or text box to a header, and it will repeat on all pages using that header. See http://wordfaqs.mvps.org/AnchorToHeader.htm.

Oh no. I want a object/section to be static on the page/screen while I scroll down the page (lets say the document is only one long page). It can be outside of the page borders (on the right side)

Would a text box dragged into the left or right margin work for you?

I'm not sure I understand what you mean or how to do so.
Just drag the text box into the margin? it still stays at that location relative to the page, that is - it moves with the page, disappears from view when I scroll down

Strictly speaking, an anchored object stays with the text paragraph where its anchor resides, but it makes no difference in this case.

Word simply can't do what you are hoping for, I'm afraid.
