Pascal,

Something else is wrong. `encoding` *is* a legal parameter to `open`: 
https://docs.python.org/3/library/functions.html#open

As for keyboard shortcuts, it depends on what shortcuts you mean. If it's something like ctrl vs. command 
make sure that you use GDK_MODIFIER_INTENT_PRIMARY_ACCELERATOR instead of GDK_CONTROL_MASK. If you use 
accelerator groups other keys can be customized with an accelerator map file; if not you'll have to hand-code 
them one by one.

OTOH if you want to use the keybindings from system preferences you'll have to code that yourself, AFAIK Gtk 
doesn't do that.
