iPad users with a Magic Keyboard, Smart Keyboard, or external keyboard can use a keyboard shortcut to launch Quick Notes on the iPad from anywhere. This may be preferable to some users than using the swipe gesture to use Quick Notes on the iPad.
If you’re familiar with using the fn+Q keyboard shortcut to summon Quick Notes on the Mac, then you’ll find this iPad trick to be familiar and easy, except you use the Globe key and Q key on the iPad.
