The following 9 Mac keyboard shortcuts will help you get around OSX that much quicker and easier. These are not the Command + C / V to copy and paste but a little more obscure. The plan is that by learning these you’ll be able to get things done a little quicker.
Command + W
Command and W closes the active window but not application. This is useful if you are working on a document have finished on it and want to move onto something else.
Command + Q
Command and Q quits the active application. This saves you having to click on the application name in the toolbar and then select Quit.
Command + H
Command and H hides the active window. This saves you having to use the minimise button and is a quick way of getting something off screen.
Command + F3
Command and F3 neatly moves open windows out of the way. Great for seeing your desktop again and re gaining focus if you have a lot of applications running.
Option + Command + D
Pressing Option, Command and D at the same time hides and unhides the dock. This can be particularly useful on a laptop.
Shift + Command + 3
Pressing Shift, Command and 3 together takes a screen shot and then deposits the results in a file on your desktop – Equivalent to Print Screen on Windows.
Shift + Command + 4
Pressing Shift, Command and 4 together supplies you with a cross hair to take a snippet of the screen and drop it into an image file.
1, 2, 3, 4 etc…
If you are playing a video then pressing the number keys will move that video on by increments of 10%. So if you want to get half way in press 5. And 0 takes you back to the start.
Command + R at bootup
Holding down Command and R when your Mac is booting up (before the Apple logo appears) takes you into Recovery Mode. This is useful for troubleshoot an issue with your Mac or if you wanted to do a whole system restore from Disk Utility. Probably not one of the keyboard shortcuts you will use that often but worth remembering as it might just save your bacon.
