Unable to move to a previous point in Emacs

Let's assume that I am at manual A. I press

enter

and I am now at manual B.

How can you return to the previous manual by one command in Emacs?

From stackoverflow

• Try typing "C-h m" to get a mode list in the help window, there you'll find

  ...
  C-c C-b  help-go-back
  ...
  

  which seems to work.

  Masi : Thank you for your answer!

• The subject is a bit misleading. You don't really want to return to the previous point but view the previously browsed manual.

  But while editing, if you jump across the buffer and then want to move the point to the previous place, you can type C-x C-@ which runs pop-global-mark.
