This is typically to finish an "entry" and begin the desired process, and is usually an alternative to pressing an OK button . </P> <P> The "return" key is often also referred to by many American groups (and even marked) as the "enter" key, and they usually perform identical functions; however in some particular applications (mainly page layout, word processing and in typewriting), "return" operates specifically like the carriage return key from which it originates . It normally has an arrow pointing down and left (⏎ or ↵), which is the symbol for carriage return . In contrast, the "Enter" key is commonly labelled with its name in plain text on generic PC keyboards, or with the symbol ⌤ (U + 2324 up arrowhead between two horizontal bars) on many Apple Mac keyboards . </P>
