Here's an updated patch:
I decided to go with 'c' and 'v' for Back and Forward since these keys
are in the same place on most localized keyboard layouts (sorry, dvorak
users) (as JDH pointed out, I could not use 'z' and 'x' because 'x' is
used as a modifier in Pan/Zoom mode)
I've added a ReST table detailing all of the key bindings as per JDH's
suggestion.
I included 'g' and 'l' for toggling grid and y scale under the heading
of "In axes only" though there's probably a better way of saying that.
Not sure if those belong there, but they seem to have not been
documented elsewhere ( same with 'f' for fullscreen)
navigation_toolbar.rst compiled and looked fine with rst2html.py and
rst2newlatex.py. The bullets ('- ') created extra vertical whitespace in
the table when I ran latex on the rst2latex.py output. If that's a
problem, those can be replaced with '-- '
looking forward to your feedback,
Paul Ivanov

If you are using :mod:`matplotlib.pyplot` the toolbar will be created
automatically for every figure. If you are writing your own user
interface code, you can add the toolbar as a widget. The exact syntax
