(user created) shortcuts
#98 asked for a new shortcut to be added. While it is easy to implement them, we should consider if it is a good idea to add arbitrary shortcuts. First it should be explored which conditions apply for shortcuts to be included per default (maybe a shortcut is also used in other browsers and thus is expected by the user).
Then it seems suitable to think about user created shortcuts, if they are necessary and how to implement them.
Personally I find the reasoning that "other browsers have it, so angelfish should also have it" kind of weak, yet again I am full on board with customizing your daily driver (e.g. your browser), so I think we could define a "default set" of available shortcuts and allow proper customization, if users want more stuff.
