What is the "Return Key" in the Computer?
Return key is the name of a key of the computer keyboard, it's the Enter key found in the alphanumeric area. Normally, this key is simply called the "enter key." The term "return key" is used to differentiate this enter key from the other "enter key" which found in the numpad. That other "enter key" is never called "return key." Only the one in the alphanumeric area is the "return key."
Pressing the Return key while typing a text breaks the current line (inserts a new line character). The Return key activates buttons that have keyboard focus, and behaves opens files that are selected in a file manager (behaves like a double click).
