as an addition to the toolbar (or as an alternative for users who want to turn it off), i think shortcut keys and a right-click menu for the figure window would be a useful addition to mpl. some suggested shortcut keys, (ctrl+)s = save as... z = zoom to rectangle p = pan (and zoom) alt+right arrow, backspace = back alt+left arrow = forward esc, ctrl+w = close figure window we already have the neat f for fullscreen. |

That's a great idea! If this were implemented, I'd like to see a set of emacs-like key-bindings. Heck, if someone points me to the right place in the code, I'll do it myself. E |

Never one to turn down free help...
The code is lib/matplotlib/backend_bases.py in FigureManagerBase.key_press
def key_press(self, event):
# these bindings happen whether you are over an axes or not
#if event.key == 'q':
# self.destroy() # how cruel to have to destroy oneself!
# return
if event.key == 'f':
self.full_screen_toggle()
if event.inaxes is None:
return
# the mouse has to be over an axes to trigger these
if event.key == 'g':
event.inaxes.grid()
self.canvas.draw()
elif event.key == 'l':
event.inaxes.toggle_log_lineary()
self.canvas.draw()
Some events like 'f' are applicable anywhere in the figure and some
are only appropriate over and axes. event.inaxes is the axes the
event occurs over, or none.
If you want to simulate clicking the toolbar, you need to call the
appropriate toolbar method. The class NavigationToolbar2 is in the
same module, eg toolbar.home(), toolbar.press_zoom(event). For funcs
that need an event, you should just be able to pass in the key event
you get in key_press.
You can access the toolbar as self.toolbar, where self is the
FigureManager instance.
Have fun!

In backend_bases.FigureManagerBase you can see how the full_screen_toggle event is added and handled. 'f', 'l', and 'g' seem reserved right now. One note, I believe modifier keys aren't supported in a natural way right now, so to catch "ctrl+s" for example could be a pain. Just pressing "ctrl" would generate an event. All the modifiers states would have to be maintained manually, I believe.

Good point. The first thing to be done is to add support for this in
the key event itself, by modifying FigureCanvasBase to track the state
of the modifier keys and add a modifier attr to the KeyEvent, so one
could do, eg
if event.key=='left' and event.modifier=='alt':
blah
Basically, you would want to add some state vars (_inalt, _inctrl,
_inshift) to FigureCanvasBase, and monitor event.key in
FigureCanvasBase.key_press_event and
FigureCanvasBase.key_release_event. I would add a new kwarg to
KeyEvent like modifier=None that would be overrridden depending on the
_in* attrs.
Any takers on this one?

That isn't the right approach, actually, because it doesn't support
multiple modifiers. I think the better approach is to add attributes
alt, ctrl and shift which are booleans, eg one would do
if event.alt and event.key=='x' :
blah
or
if event.alt and event.ctrl and event.key=='x' :
blah
