I think the real power comes when you have both a GUI and an initiative (though not always correct) keyboard input methods. Point and click can be slow, and if you are taking notes while attending a lecture, you probably don’t want to waste your valuable focus looking for the correct icon to write the thing, you just want to type `||a||^2` and hope it does the right thing (and if it doesn’t your temporary markup is obvious enough that you can return to it later).
