How to insert "hints" on where I am in a document?

[Iuliia]

Hi everyone!



I have been recently writing a 155 pages manual with lots of similar sections. My problem now is, when I am going through the open printed document, it is difficult to understand where I am reading.

So I wanted to insert some kind of "hints" or "indicators" or I don't know the correct word for it on the write or top margin that would indicate my position in the document (e.g. "Section 1: Menu 12" - heading of the section).

I would appriciate if someone can share his ot her knowledge on this.

Thank you.
