Mission Control offers a way to see all open windows on a Mac easily and from a single screen, but if you have a ton of windows open then the thumbnails shown in Mission Control can be quite small. Thus, you might be wishing you could see a larger preview of the thumbnail preview tile as seen in Mission Control. Well it’s your lucky day and that wish has been granted.
You can use a great little trick to instantly get a larger preview of any thumbnail window seen in Mission Control using none other than Quick Look. Yes, the same Quick Look that allows you to see previews of files and items in the Finder can also preview your Mission Control windows.
Here’s how this works:
1: Enter Mission Control as Usual
Use the three-finger swipe up gesture to enter Mission Control, or the keystroke or gesture that you use to access Mission Control on the Mac.
2: Hover Over a Tiled Thumbnail in Mission Control with the Cursor
Next you want to drag the mouse cursor over the thumbnail of a Mission Control window that you want to preview.
Just hover the mouse over the window, don’t click. If you click, it selects that window and brings it to the forefront instead.
3: Hit the Spacebar to Preview the Mission Control Thumbnail as a Larger Window
Hit the spacebar in Mission Control to preview the item that the cursor is hovered over.
This is just like you’d hit the Spacebar to enter Quick Look in the Finder on a file.
4: Hit Spacebar Again to Dismiss the Larger Thumbnail Preview in Mission Control
You can dismiss the preview without existing Mission Control by hitting Spacebar again.
The embedded video below demonstrates how this feature works once you’re inside Mission Control view on the Mac, but it’s best to try out yourself.
This excellent Mission Control usability tip works all the time, but it’s often best used when you have a lot of windows open and you are looking at tiny thumbnail previews which are ambiguous. When that happens, just hover your mouse cursor over and hit spacebar to check it out in a larger view – on a large screen Mac you can even see full sized previews of the window in question this way.
