Almost everything you need when viewing pictures with MComix can easily be accessed by simply hitting the right (as in "correct") key for it. However, if you want to reset the zoom factor to 100%, you have to hit at least two keys: Ctrl + 0. It would be cool if the 0 key (or some other key, how about O (as in: "original")?) alone would reset the zoom factor.
Maybe you can keep Ctrl + 0 to do this, too. But this does not seem to be that easy according to this: https://sourceforge.net/p/mcomix/feature-requests/40/#d0ac
Thank you in advance!
