If you are like me and find using the touchpad or mouse too slow and cumbersome for repetitive tasks, here are the most useful keyboard shortcuts that I use.
Command + Tab + (Shift)
Pretty much the same as the Windows version of Alt + Tab, it cycles you through your open programs. Use the addition of the shift key if you want to cycle in the opposite direction.
Command + ` + (Shift)
If you would like to cycle through your multiple open windows. I use this a whole lot with my browser.
Control + Tab + (Shift)
If you would like to move between the tabs of your browser, this is another handy shortcut.
Command + Option + Control + Eject
Use the keyboard combination of Command + Option + Control + Eject to instantly shut down your Mac. (And I mean instantly — make sure you've saved any open files!) This is a great time saver because it bypasses the shut-down counter that you get when using Apple menu > Shut Down (shown above). You can also put your Mac to sleep by pressing Command + Option + Eject.
Control + D
One thing that really irked me when I switched from Windows to Mac was the Windows delete key , the Mac's "Delete" key doesn't actually function as the delete key does in Windows. The "Delete" key on the Mac instead functions as a backspace. To remedy this, you can instead use Control + D in any text area on your Mac to delete from the front of the cursor.
Command + Control + D
When reading or writing, Ioften need to quickly look up the meaning of a word, OSX has a really nifty built in dictionary that solves this issue. It has save me a ton of time having to open up a browser window to look up a definition. With your mouse cursor over top of the word you'd like to look up, press Command + Control + D. A dialog will then pop up with the word defined by the built-in Mac OS X dictionary.
Command + Shift + 4 + Space Bar
To grab just a one-window screenshot, press Command + Shift + 4, then when the crosshairs appear, press the space bar. The cross hairs will change to a picture of a camera that can be placed over top of the window to be captured and clicked. The resulting window-only screenshot will appear on your Desktop.
