[OT for this discussion but just wondering if Jambunathan's suggestions may work here] There has been this question asked both on the emacs and on the python list Just excerpting from http://groups.google.com/group/comp.lang.python/browse_thread/thread/acb0f2a01fe50151# I am using python-mode to write python code in Emacs, and when I use the useful C-c C-c key combination to interpret the buffer, Emacs always opens another window inside the window I am using. I prefer using Emacs split in two windows (one on each physical screen) where I program in one of them and use the Python interpreter in the other. Is there a way I can tell Emacs to use the *Python* buffer in the Window that is already open instead of creating a new one?
