I've always hated the Fn keys. Give me dedicated home/end/pgup/pgdnkeys any day. But then I got a new laptop (XPS 13), and used it almost exclusively for 6 months.
Now I go back to my desktop, and I'm unable to code in it without constantly hitting Windows+left, Windows+up, etc etc. Which does nothing useful, other than to move windows to one side of the monitor etc.
Is there something I can do to re-map Windows+up to page up, Windows+left to home, etc?
