Backspace Move the cursor back one space, deleting the character to the left.
Enter Ends a line of keyboard input or executes a command. (This key may be called the Return key in some of your software documentation.)
Caps Lock Changes the letter key from lower to uppercase; changes back to lowercase when pressed again.
