Resizing Windows in Mac OS X with Modifier Keys
In modern versions of Mac OS X, the ability to resize any window from any corner or side of is possible; just grab onto it, and when your cursor turns into the little double-sided arrow, start dragging. That’s a great addition in and of itself, but the resizing feature gets even better when some modifier keys are applied, which can further help adjust and direct resizing of windows in OS X.
You’ll use a click and drag motion with the cursor in addition to the modifier keys to get these tricks to work.
Window Resizing Modifier Keys for Mac OS X
- Click and Hold Shift – Resizes the window in the direction you are pulling, while maintaining the windows existing aspect ratio
- Click and Hold Option – Resizes the window from the side you are dragging as well as the side directly opposite
- Click and Hold Option+Shift – Combines both to resize the window in all directions while maintaining the aspect ratio, from the center of the window outward
The Option+Shift drag trick is particularly useful if you encounter a window that is too big to fit onscreen, since it can be used to bring the window titlebar back onto the display of a Mac.
These modifier keys should work in every somewhat modern version of OS X, from Lion through El Capitan and beyond. I had known about the first two, but the last combo was found on MacGasm, so head’s up to those guys for the tip.
