In SGML, HTML and XML documents, the logical constructs known as character data and attribute values consist of sequences of characters, in which each character can manifest directly (representing itself), or can be represented by a series of characters called a character reference, of which there are two types: a numeric character reference and a character entity reference.
This notably did not include XML's ' (') entity prior to HTML5. For a list of all named HTML character entity references along with the versions in which they were introduced, see List of XML and HTML character entity references. Unnecessary use of HTML character references may significantly reduce HTML readability.
I.e. does ' ' &Apos; and &apoS; all signify the same apostrophe character, or is only the first of the preceding list valid? For HTML character entities, there are separate definitions that differ only by case (e.g. Ø and ø for an upper-/lowercase letter "O" with a forward slash (Ø and ø).
This page lists codes for keyboard characters, the computer code values for common characters, such as the Unicode or HTML entity codes (see below: Table of HTML values"). There are also key chord combinations, such as keying an en dash ('–') by holding ALT+0150 on the numeric keypad of MS Windows computers. The HTML codes can be used where a ...
The format is the same as for any entity reference: &name; where name is the case-sensitive name of the entity. The semicolon is required. Because numbers are harder for humans to remember than names, character entity references are most often written by humans, while numeric character references are most often produced by computer programs.

A numeric character reference (NCR) is a common markup construct used in SGML and SGML-derived markup languages such as HTML and XML. It consists of a short sequence of characters that, in turn, represents a single character. Since WebSgml, XML and HTML 4, the code points of the Universal Character Set (UCS) of Unicode are used.
