Both the Logitech and Brydge keyboards have a row of function keys at the top that the Magic Keyboard lacks. Brightness and volume control are two very popular ones. One key combo I use often on the MKB is Command-H to return to the home screen. There are a few others that are not all that helpful, but it seems like Apple would add some more of these combos to make up for the lack of the function keys on the MKB. Are there any that you use currently which you find particularly handy?
