1. The Shift key is a keyboard modifier key that allows a user to type a single capital letter. For example, pressing and holding the Shift key while pressing the letter a key would generate a capital A. On US keyboards the Shift key is the second largest key located on both the left and right-hand of the keyboard, below the Caps lock key, and Enter or Return key. The picture is a close up view and example of the Shift key.
Tip: Unlike the other modifier keys the Shift key is also found on Apple computer keyboards and performs the same function as the PC. With Apple keyboard shortcuts, the Shift is represented as an up arrow, similar to that shown in our example picture.

How to use the Shift key
To use the Shift key to capitalize letters press and hold down the Shift key and while continuing to hold down the key push the letter you want to capitalize. On U.S. keyboard and other similar keyboards you can also hold down the Shift key and press the number across the top of the keyboard to get the symbols (e.g. !, @, #, and $) on those keys.
Tip: On most computers (except those running OS X) if the Caps Lock key is enabled and you press the Shift key and a letter the letter will be lowercase.
The Shift key is also used with shortcut keys. For example, holding down the Shift key and pressing your arrow keys will highlight text in the direction of the arrow key you press. Below are other examples of shortcuts that use the Shift key.

Why are there two Shift keys?
There are two Shift keys on a computer keyboard to help with capitalizing letters on both sides of the keyboard. For example, if you wanted a capital "z" you use your pinky on your right-hand to press and hold down Shift and then press the "z" key with your left-hand to make a capital "Z". Trying to make a capital "z" with only the left-hand would require you to move your hand since the pinky cannot press both keys at the same time.
