My biggest issue with the MPB is that if you accidentally press Option+[Any touch bar icon] the System Preferences will open.

This happens quite a lot for me on a keyboard with Swedish layout, where it is easy to accidentally rest my right pinky on the touch bar when when writing chars such as { and [.

    * "(" is Option+8
    * "{" is Option+Shift+8

I had no idea that alt + Touch Bar opens the display preferences or the sound preferences. Quite a useful tip!

(fyi to those of us holdouts..)

On the older ones with real keys it does the same thing:

alt+volume => opens sound prefs

alt+brightness => display prefs

alt+mission control => ..

alt+keyboard backlight => keyboard

also, unrelated but occasionally useful.. alt+shift allows you to adjust volume/brightness in fractional increments.
