period, semicolon, brackets, parenthesis and so on. Also, all of the mathematical

Special keys on a PC Keyboard
• Alt key – Short for Alternate, this key is like a second control key.
• Arrow Keys – Most keyboards have four arrow keys that enable you to move the
cursor (or insertion point) up, down, right, or left. Used in conjunction with the Shift
or Alt keys, the arrow keys can move the cursor more than one position at a time, but
this depends on which program is running.
• Backspace key – Deletes the character just to the left of the cursor (or insertion
point) and moves the cursor to that position.
• Caps Lock Key – A toggle key that, when activated, causes all alphabetic characters
to be uppercase.
• Ctrl key – Short for Control, this key is used in conjunction with other keys to
produce control characters. The meaning of each control character depends on which
program is running.
• Delete Key – Sometimes labeled Del, deletes the character at the current cursor
position, or the selected object, but does not move the cursor. For graphics-based
applications, the Delete key deleted the character to the right of the insertion point.
• Enter Key – Used to enter commands or to move the cursor to the beginning of the
next line. Sometimes labeled Return instead of Enter.
• Esc Key – Short for Escape, this key is used to send special codes to devices and to
exit (or escape) from programs and tasks.
• Function Keys – Special keys labeled F1 to F12. These keys have different meaning
depending on which program is running.
