What Is the Keyboard Shortcut for Sleep Display Without Eject Key? [duplicate]

Solution 1:

(At least on the Retina display MacBook Pro) use the Power button the same as you previously used the Eject button. So Control ⌃+Shift ⇧+Power puts the display to sleep and Command ⌘+Option ⌥+Power puts the machine to sleep.

Solution 2:

Found two options:

  1. Use BetterTouchTool add global keyboard shortcut and choose Sleep Display.
  2. Use Hot Corners (System Preferences -> Desktop & Screen Saver) and choose Put Display To Sleep. (You can hold down Command ⌘ and then it will only work when you're in the selected corner and while is pressed.)
