Apple just announced the new MacBook Pro's and they've thrown out the function keys (and Escape key!) and replaced them with the Touch Bar. So, we've lost touch typing function keys and escape key.
You can expose the function keys by holding down the 'fn' key, but that makes function key combos much tougher. So it looks like we need a new key map that eschews the function keys. Since that is a huge hit to the range of usable keys, I would suggest moving many of those functions to a command interface.
The one benefit to this is that the touch bar is programmable. So context sensitive features can be moved there (debug step over, etc.).
