What is the use of cursor movement keys in a keyboard?
Cursor control keys move the cursor from one place to another on
the display screen. The cursor is the indicator on the display
screen that lets the user know where the next entry will be made.
Cursor control keys have an arrowhead printed on them pointing in
the direction that the key will move. Some keyboards have a
separate set of keys for cursor movement; others have the cursor
movement keys incorporated into the numeric keyboard. As long as
the NUM LOCK key is OFF, the cursor movement keys function. Some
software packages use the cursor control keys in combination with
each other or with other keys to increase the number of ways and
the speed with which you can move the cursor. Another cursor
movement key - the SCROLL LOCK/BREAK key - controls screen
scrolling. When in the BREAK mode and used in conjunction with the
CTRL key, the SCROLL LOCK key will interrupt program execution.
