 In pocket calculator-like programs (for example, Microsoft Calculator for Windows users), the enter key of the numeric keypad acts like the "equal to" (=) button to obtain the result of the previously entered operations.In graphical computer applications, the enter or return key is often used to close and submit a form the user is editing.Usually the default "OK" or "Save" button on a form is highlighted and sometimes shows a Return symbol, giving a subtle visual clue that the user has the option of clicking the button or simply pressing Enter.
