Keyboard Combinations
Redo
Windows users: While most of you know that the Ctrl + Z is used to undo an action, did you know that there is a keyboard combination that does just the opposite? Pressing Ctrl + Y will redo the action that you undid.
For Mac users: Command + Shift + Z
Screenshot of active window
For Windows users: The Print Screen (PrtSc) key on your keyboard is used to take snapshots of the entire screen. But if you want to quickly take a screenshot of just the active window, press Alt + Print Screen. This will eliminate the need to edit the screenshot to cut out just the active screen.
For Mac users: Command + Shift + 4, then press the Space key. This will change the cursor from the crosshair to the camera icon. Now click on the window you wish to capture.
