Dictionary of Computer and Internet Terms: Enter key
Enter key
the key on a computer keyboard that you press at the end of each line in order to send the contents of that line into the computer. On most keyboards, the Enter key is the same as the Return key. However, IBM 3270-series terminals make a distinction: the Return key starts a new line, but the Enter key sends the contents of the whole screen to the computer.
Under windowed operating systems, pressing the Enter key is usually equivalent to clicking on the currently selected icon or other highlighted item.
