Viewing One Outline in Multiple Views
-------------------------------------
You can display two views of a single outline at the same time, in
different windows. To do this, you must create an indirect buffer using
`M-x make-indirect-buffer'. The first argument of this command is the
existing outline buffer name, and its second argument is the name to
use for the new indirect buffer. Note:Indirect Buffers.
Once the indirect buffer exists, you can display it in a window in
the normal fashion, with `C-x 4 b' or other Emacs commands. The Outline
mode commands to show and hide parts of the text operate on each buffer
independently; as a result, each buffer can have its own view. If you
want more than two views on the same outline, create additional indirect
buffers.
