ENTER key(The key that is used at the end of a line or command to instruct the computer to process the command or text. In word processing programs, the Enter key is used at the end of a paragraph. Also called: Return key)
PAGE UP key(" A keyboard key (often labeled "PgUp") that is often used to move the cursor up to the top of the previous page or a specific number of lines. Its function may vary in different programs.")
SCROLL LOCK key(On the IBM PC/XT and AT and compatible keyboards, a key on the top row of the numeric keypad that controls the effect of the cursor control keys and sometimes prevents the screen from scrolling. On the enhanced and Macintosh keyboards, this key is to the right of the function keys on the top row. Many modern applications ignore the Scroll Lock setting)
TAB key(A keyboard key, often labeled with both a left-pointing and a right-pointing arrow, that traditionally (as in word processing) is used to insert tab characters into a document. In other applications, such as menu-driven programs, the TAB key is often used to move the on-screen highlight from place to place)
ALT key(A keyboard key that is used in conjunction with another key to produce some special feature or function and is typically marked with the letters Alt)
ESC key(A keyboard key that sends the escape (ESC) character to the computer. Often this key moves the user back one level in the menu structure or exits the program)
PAGE DOWN key(" A keyboard key (often labeled "PgDn") that is often used to move the cursor down to the top of the next page or a specific number of lines. Its function may vary in different programs.")
PRINT SCREEN key(A key on IBM PC and compatible keyboards that normally causes the computer to send a character-based "picture" of the screen contents to the printer)
SHIFT key(A keyboard key that, when pressed in combination with another key, gives that key an alternative meaning, for example, producing an uppercase character when a letter key is pressed. The SHIFT key is also used in various key combinations to create nonstandard characters or to perform special operations)
Windows button(A tablet hardware button with the Windows logo on it that's similar to the Windows key on a keyboard. Pressing the Power and Windows buttons simultaneously is the equivalent of pressing Ctrl+Alt+Del)
INSERT key(" A key on the keyboard, labeled "Insert" or "Ins", whose usual function is to toggle a program's editing setting between an insert mode and an overwrite mode, although it may perform different functions in different applications.")
DELETE key(On IBM and PC-compatible computers, a key whose function changes depending on the application program. Usually it erases the character under the cursor, although in some applications it can erase selected text or graphics)
