What is the Shift Key on the PC, and What does It do?
The Shift key is a key of the computer keyboard used to type upper case letters, symbols written at the upper part of other keys, and to execute commands with keyboard shortcuts and modify the function of mouse clicks.
The Shift key doesn't do anything by itself when pressed alone. It's a modifier key meant to be combined with other input.
If the caps lock is activated, letters are upper case by default, so the Shift key makes them lower case instead. Note that the the caps lock only makes letters upper case by default, it doesn't make symbols the upper ones by default. To type upper symbols, you still need to hold the Shift key.
Where is the Shift Key on The Keyboard?
The left Shift key is located on the left side of the keyboard, above the Ctrl key, and below the Caps Lock key. There also a right Shift key on the right side, above the right Ctrl key, and below the Return (Enter) key.
In some keyboards, the Shift key may take the appearance of a upward arrow symbol without the word "shift" printed on it.
