I'll try to use the more common Windows/MacOS terms for it, but in emacs I often have the same file opened in two different panes within one window or two separate windows. I do this when I want to be looking at one part of a file while editing another.

Markers are used to mark a different point in the file and one can pop their location to a previous mark.

Putting cursors within the document does not preclude supporting different cursors for different windows.
