Storyboard Zoom In/Out Keyboard Shortcut

Question

What shortcut key combination can I use in Xcode to zoom in and out? Yes, I know this is a silly question but a Google search didn\'t give me any result. Even the Xcode keyboard

Answer 1

The accepted answer from Rohit works, but the menu option simply says Command+Alt+{ and Command+Alt+} on XCode 5, i.e. Alt is not necessary. Funny thing is other SO answers said zoom was NOT possible, maybe added in later Xcode 4x or 5?

Apple loves whitespace and wide margins, but if you have more than a few screens, zooming is absolutely essential even on 4k displays!
