This is dim, but I've forgotten how to do this, and I can't work it out, sorry:
I'm in python mode with elpy, and I want to run the function
in a python buffer, to see what it does
won't work, because the function is not a command (it has no
(python-nav-beginning-of-defun) in a buffer and using
C-x C-e will disturb the buffer and move the point.
I seem to remember that there's some way that I can type
(python-nav-beginning-of-defun) in a mini-buffer somewhere, and see what it does to the python buffer, without disturbing the buffer.
Can anyone tell me what it's called / what the magic keys are?
