You can use the
clone-buffer (M-n) command. It lets you navigate through each buffer independently.
<menu-bar> <Info> <Clone Info buffer> runs the command clone-buffer
(found in Info-mode-map), which is an interactive compiled Lisp
function in ‘simple.el’.
It is bound to M-n, <menu-bar> <Info> <Clone Info buffer>.
(clone-buffer &optional NEWNAME DISPLAY-FLAG)
Probably introduced at or before Emacs version 21.1.
Create and return a twin copy of the current buffer.
Unlike an indirect buffer, the new buffer can be edited
independently of the old one (if it is not read-only).
NEWNAME is the name of the new buffer. It may be modified by
adding or incrementing <N> at the end as necessary to create a
unique buffer name. If nil, it defaults to the name of the
current buffer, with the proper suffix. If DISPLAY-FLAG is
non-nil, the new buffer is shown with ‘pop-to-buffer’. Trying to
clone a file-visiting buffer, or a buffer whose major mode symbol
has a non-nil ‘no-clone’ property, results in an error.
Interactively, DISPLAY-FLAG is t and NEWNAME is the name of the
current buffer with appropriate suffix. However, if a prefix
argument is given, then the command prompts for NEWNAME in the
This runs the normal hook ‘clone-buffer-hook’ in the new buffer
after it has been set up properly in other respects.
