Functions of the keyboard keys
Key Description
Numeric keypad
area Contains the keys found on a typical calculator. Use the
numeric keypad area to type numbers or to perform
mathematical calculations such as addition and subtraction.
Note that you must press the Num Lock key to activate the
numeric keypad. (When you do so, the Num Lock indicator
will be on.) Press the Num Lock key again to deactivate it.
Navigation keys The Left/Right/Up/Down arrows are devoted to move the
cursor on the screen and also function as the Home, End,
Page Up, and Page Down keys, respectively.
Correction keys The Insert, Backspace, and Delete keys enable you to make
corrections in your documents.
Function keys The 12 function keys along the top of the keyboard are used
to perform designated tasks. For example, in many
applications, F1 is the Help key. The task associated with
each function key may vary from one application to the next.
Escape key The Esc (Escape) key is used to cancel commands.
Print Screen key The Print Screen key takes an electronic snapshot of the
screen and places it in the Windows® Clipboard. You can
then paste the screen shot into a document and print it.
Operator keys Several keys are always used with at least one other key:
Ctrl, Alt, and Shift. When held down with another key, the
Ctrl (Control) and Alt (Alternate) keys offer another way to
give commands. For example, in many applications, instead
of choosing the Save command from a menu, you can hold
down Ctrl and press S (referred to as Ctrl+S). The Shift key
operates the same way as on a typewriter; it is used to
produce capital letters or special symbols such as @ and $.
