A
key that moves the
cursor (or
insertion point) to the beginning of the next line, or returns control to whatever
program is currently
running. After a program requests information from you (by displaying a
prompt), it will usually not respond to your
input until you have pressed the Enter or
Return key. This allows you to correct typing mistakes or to reconsider your entry before it is too late. In many
applications, pressing the Enter key moves the cursor to the next
field. In
graphical user interfaces, pressing Enter activates the currently
selected button or
option.
