different buffers on same file?

different buffers on same file?

[kj]

Is there any way to have more than one buffer visiting the same
file?  I tried renaming a buffer and "find-file"-ing the same file
again, but Emacs did not create a new buffer; it just re-used the
original buffer despite the name change.

My immediate need for this is that I'm trying to read a huge (0.5
MB) source code file, 95% of which consists of the first leg of a
single if statement (horrible programming, I know), and it would
be very useful if I could simultaneously have several
buffers/windows/frames that were narrowed (C-x n n) to various
sections of this file.  Since narrowing is a per-buffer property,
I need to have several buffers opened on the same file if I want
to do this.

Thanks!

`M-x clone-indirect-buffer <RET>'

Just the ticket!  Thank you.

In my version of emacs, GNU Emacs 20.7.1, the function is called
make-indirect-buffer. I use it with "outline-mode" to be able to
collaps all threads in one window and still be able to have som
threads visible in an other.
