The amazing ways the function keys F1 to F12 can save you a ton of time

If the only time you use these keys is when the computer starts acting up and you just start smacking every key in reach to (hopefully) fix the problem, you’ve been missing out on some major time-saving tricks.

*Note: Computer Hope notes that the function keys on your computer may have additional uses when you hit the FN (function) key plus the selected F-key. Also, make sure you check your computer manual to see if your model offers any alternate functions.

F1: 
Need help? The primary function of the F1 key is to open up the support menu for any program you are in, according to Tech Worm. You can also hit the F1 key and the Windows button for Microsoft Help and Support.

F1 will also allow you to enter CMOS setup. On some computers (like mine), it acts as the mute button for volume.

F2: 
This key lets you rename a file or folder on your computer, according to Bright Side. (Saves a few seconds over hitting the right button on your mouse 15 times to get the box to actually highlight.)

This key may also act as a volume button.

Hit Alt+Ctrl+F2 to open a document in Microsoft word (adding this one to my arsenal right now!)

Ctrl+F2 opens print preview

F3: 
Use this function to open a search window in a specific program (like Word).

Realize you need to capitalize a bunch of words in your document? Highlight the word and hit Shift+F3 to capitalize the beginning letter of a word.

Hit the Windows Key+F3 to open an advanced find window in Outlook.

In Apple, the F3 key will open Mission Control.

F4: 
Whether you accidentally opened a site you don’t want to see or you’re playing around on Facebook at work, Alt+F4 or Ctrl +F4 could save your butt. It will automatically close current windows (without saving).

Just hit the F4 key while on the internet to open the address bar without touching your mouse.

In Microsoft word, the F4 button will repeat the last action you performed.
