The ability to view multiple images in one set is new to Lion and very much quicker than opening the same number of files in any given app (no matter how fast your Mac performs). It takes another button press after your initial Spacebar hit to activate the feature and it’s not quite as obvious as you might think. We only found it recently ourselves, but we’ll show you how it can improve your workflow. Here is the next OS X tip you can’t live without…
Step 1: Get selecting
Drag your mouse over a batch of files. Any files. Or use the classic single- click on one file and then hold the Shift key and click the last one in the list. Once all the files are selected, hit the Spacebar.
Step 2: Simple view, hidden feature
Up at the top of the Quick Look window is a tiny view button with four little windows in it. Click this to expand the view and see all the items in your selected group of files.
Step 3: Better than a thumbnail
This is a great way to quickly view a batch of files to determine their contents. It’s much easier to sort through than smaller thumbnails on your Desktop. Return to the main view by clicking a file.
