Simply hit Shift+W to enter into Presentation Mode. By default, InDesign uses a solid black background. But you can change to a neutral gray background by hitting the letter G, or white by hitting W. If you want to switch back to solid black, hit B.

Of course, to exit Presentation Mode, simply hit the ESC key or Shift+W again.

Photoshop CS6 offers interface brightness flexibility

Simply hit Shift + Function + F1 to lighten the interface, or Shift + Function + F2 to darken it.

Instead, to switch to another tool, Command + Click on the text frame or hit Command + Shift + A to exit text editing mode. You can then hit the appropriate letter to switch tools, such as P for the Pen tool, or M for the Rectangle tool.

Rather than keep the Text Wrap panel open or (worse yet) keep opening and closing it as needed via the menubar, you can simply Option + Click the icon in the Tools panel. This will pop the panel open so you can access more of the Wrap features.

Simply copy the text as you normally would (Command + C), then move to where you want to paste the text and hit Command + Shift + Option + V. Your text will be pasted with no formatting whatsoever.

This is particularly useful when copying colored text with one font and pasting it into a new document that uses completely different fonts and colors.

A simple keyboard shortcut allows you to "eyeball" the distribution of objects

If you would rather “eyeball it,” you can do so simply by selecting your objects, grabbing one of the selection handles on one of the objects and hold the space bar down as you drag the handle. Rather than resizing your objects, the space between the objects will increase or decrease accordingly.

Selecting individual InDesign Table cells, and the content in them, is easy with the keyboard

If you use Tables in your InDesign document, selecting individual cells with the mouse can make your fingers sore. Instead, use the Tab and/or Arrow keys to move between them. Maybe you already knew that. But did you know that you can click the cell you wish to work with and hit the ESC key to select the entire cell (perhaps to fill the cell with a color) and hit ESC a second time to select the content inside the cell (to change the font, for example).

A quick shortcut to check and uncheck all items in your playlists

If you have a lot of items in a music playlist and you want to check or uncheck them all, you can save yourself the time and trouble of doing it one-by-one simply by clicking the checkbox of any song in the playlist while holding the Command key down. Doing so will check or uncheck all the items in the playlist at once.

Rather than selecting your object and using the Rotate tool in the Tools panel, simply move your cursor to just outside the corner of your object with the Selection tool to reveal the hidden rotate icon – then just click and drag the mouse to rotate.

Of course if you’re looking for a keyboard shortcut, you can always just hit the R key to select the Rotate tool without visiting the Tools panel.

Either way, you can rotate multiple objects without grouping them – yet another time saver!

The two faces of Mac OS X's Quick Look feature: Regular and full screen

But OS X has the annoying habit of displaying the selected graphic at an arbitrary size on your screen (as seen on the left in the image above). You can then hit the double-arrow icon in the Quick Look preview to zoom it to full screen. This is doubly annoying for anyone with a large screen because not only do you not use the full size of your screen, but you then have to move your mouse all the way down to the bottom of the screen to click the icon.

Thankfully, you can avoid all that mousing around and enjoy a full screen Quick Look preview (as seen on the right in the image above) simply by using the keyboard shortcut of Option + Space bar instead of just the Space bar.

You can also view a slideshow in full screen mode by selecting multiple files before entering Quick Look. To exit full screen Quick Look, simply hit the ESC key in the upper left of your keyboard.
