I completely agree about the mousewheel. However, would it make sense for
OS X to combine command with mousewheel? I have never seen that before. I
am not sure if I can bind the zoom gesture with tkinter, but I can find
out.
I also think the shortcuts are not intuitive as an OS X user, as command
should be used instead of Ctrl.
What I can do check the operating system and define the font shortcuts
accordingly. I am not sure about redefining the Menu shortcuts as that
seems like a separate issue.
