On some keyboard layouts, the return and enter key are two different keys, an artifact of the differing handling of newlines by different operating systems. As an example, on the Macintosh, the return key is the usual key, while the enter key is positioned at the lower right of the numeric key pad.

On some keyboards the enter key is bigger than traditionally and takes up also a part of the line above, more or less the area of the traditional location of the backslash key (\). In these cases the backslash is located in alternative places. It can be situated one line above the default location, on the right of the equals sign key (=). Sometimes it's placed one line"

Several other ISO 646 versions also replace backslash with characters like Ö (German, Swedish), Ø (Danish, Norwegian), ç (French) and Ñ (Spanish), leading to similar problems.

"Backspace Backspace is the keyboard key that originally pushed the typewriter carriage one position backwards, and in modern computer systems moves the display cursor one position backwards, deletes the character at that position, and shifts back the text after that position by one position. In some typewriters, a typist would, for example, type a lowercase letter A with acute accent (á) by typing a lowercase letter A, backspace, and then the acute accent key. This technique (also known as overstrike) is the basis for such spacing modifiers in computer character sets such as the ASCII caret (^, for the circumflex"

It is a toggle key: each press reverses its action. Some keyboards also implement a light, so as to give visual feedback about whether it is on or off. Exactly what Caps Lock does depends on the keyboard hardware, the operating system, the device driver, and the keyboard layout.
