The Notebook Keyboard Keys
Key Description
Numeric keypad area The numeric keypad area contains the keys found on a
typical calculator. Use this area to type numbers or to
perform mathematical calculations such as addition
and subtraction. Note the following:
❑
To activate the numeric keypad, press the Num
Lock key, which causes the Num Lock light to
come on and remain on until the numeric keypad
is deactivated.
❑
To deactivate the Num Lock key, press the Num
Lock key again, which causes the Num Lock
light to go off.
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, Back Space, 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 (Ctrl, Alt, Shift
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 $.
