Description
We currently use the add_accelerator
method from Application and from Window and according to http://lazka.github.io/pgi-docs/#Gtk-3.0/classes/Widget.html#Gtk.Widget.add_accelerator it has to be replaced:
Accelerators added through this function are not user changeable during runtime.
If you want to support accelerators that can be changed by the user,
use Gtk.AccelMap.add_entry() and Gtk.Widget.set_accel_path() or
Gtk.MenuItem.set_accel_path() instead.
