Using keyboard shortcuts can greatly increase your productivity, reduce repetitive strain, and help keep you focused. For example, to copy text, you can highlight text and press the Ctrl + C shortcut. The shortcut is faster than moving your hands from the keyboard, highlighting with the mouse, choosing copy from the file menu, and then returning to the keyboard.
Below are the top 10 keyboard shortcuts we recommend everyone memorize and use.
Both Ctrl + C and Ctrl + Insert will copy the highlighted text or selected item. If you want to cut instead of copy press Ctrl + X.
Apple computer users can substitute the Ctrl key for the command (cmd) key on their computers. For example, pressing Cmd + C copies the highlighted text.
Both the Ctrl + V and Shift + Insert will paste the text or object that's in the clipboard.
For Apple computer users use Cmd + V.
Practice
Use the above text input fields to highlight the "Cut or copy this text" text and press either Ctrl + C to copy or Ctrl + X to Cut the text. Once Cut Move to the next field and press Ctrl + V or Shift + Insert to paste the text.
Pressing Ctrl + Z will Undo any change. For example, if you cut text, pressing this will undo it. These shortcuts can also be pressed multiple times to undo or redo multiple changes. Pressing Ctrl + Y would redo the undo.
For Apple computers use Cmd + Z and Cmd + Y to undo and redo.
Use the above text input field to highlight some or all of the text and then press Ctrl + X to cut the text. Once the text has disappeared press the Ctrl + Z to undo the cut.
Tip: If you did the first example as well (cut and paste text) if you continue to press Ctrl + Z it is also going to undo that change.
Pressing Ctrl + F opens the Find in any program. Ctrl + F includes your Internet browser to find text on the current page. Press Ctrl + F now to open the Find in your browser and search for "shortcut" to find each time shortcut is mentioned on this page.
For Apple computer use Cmd + F to find.
Pressing Alt + Tab switches between open programs moving forward. For example, if you have your browser window open and other programs running in the background press and hold Alt and then press tab to cycle through each open program.
On Apple computers instead of using the Alt key use the Command (Cmd) key. For Example, Cmd + Tab to switch between open programs.
Bonus Tip: Press Ctrl + Tab to switch between tabs in a program. For example, if you have multiple tabs open in your browser now press Ctrl + Tab to switch between open tabs.
Bonus Tip: Adding the Shift key to Alt + Tab or Ctrl + Tab moves backward. For example, if you are pressing Alt + Tab and pass the program you want to use, press Alt + Shift + Tab to move back to that program.
Bonus Tip: Windows Vista, 7, 8, and 10 users can also press the Windows Key + Tab to switch through open programs in a full screenshot of the window.
