For those of us that have used emacs for a long time, it is the other items that feel foreign. And, quite frankly, I'm not sure I'm missing anything from the others.

It is annoying that Apple has a command key that I have mapped as Meta. Since that means if I try to copy something in Firefox, closed tab. That said, why are the keyboard shortcuts in so many other applications so destructive? And crappy? Browsers could be forgiven if they were just for viewing, but you edit in them a lot nowadays, such that the browser not having easily customized keyboard bindings is a laughable insult for user centric design.

(Do they even still pretend to support user stylesheets anymore?)
