In typography, a bullet or bullet point,, is a typographical symbol or glyph used to introduce items in a list. For example:
The bullet symbol may take any of a variety of shapes, such as circular, square, diamond or arrow. Typical word processor software offers a wide selection of shapes and colors. Several regular symbols, such as (asterisk), (hyphen), (period), and even (lowercase Latin letter O), are conventionally used in ASCII-only text or other environments where bullet characters are not available. Historically, the index symbol (representing a hand with a pointing index finger) was popular for similar uses.
Lists made with bullets are called bulleted lists. The HTML element name for a bulleted list is "unordered list", because the list items are not arranged in numerical order (as they would be in a numbered list).
The 1950 New York News Type Book is credited as the first style guide to include a defined use for bullets. The Type Book described it as a typographic device to be used as an "Accessory" alongside asterisks, checks, and other marks available to people making advertisements for the News. The book "neither discusses the function of bullets in advertisements nor distinguishes them from any of the other items in the 'accessories' category", but can be seen to use them as a form of dinkus in an advertising panel.[3]
Example: "Bullets are often used in technical writing, reference works, notes, and presentations". This statement may be presented using bullets or other techniques.
Bullets are often used in:
Alternatives to bulleted lists are numbered lists and outlines (lettered lists, hierarchical lists). They are used where either the order is important or to label the items for later referencing.
The glyph is sometimes used as a way to hide passwords or confidential information. For example, the credit card number might be displayed as .
There have been different ways to encode bullet points in computer systems.
Glyphs such as, and their reversed variants, became available in text mode since early IBM PCs with MDA–CGA–EGA graphic adapters, because built-in screen fonts contained such forms at code points 7–10. These were not true characters because such points belong to the C0 control codes range; therefore, these glyphs required a special way to be placed on the screen (see code page 437 for discussion).
Prior to the widespread use of word processors, bullets were often denoted by an asterisk; several word processors automatically convert asterisks to bullets if used at the start of line. This notation was inherited by Setext and wiki engines.
There are a variety of Unicode bullet characters, including:
To create bulleted list items for a web page, the markup language HTML provides the list tag . The browser will display one bulleted list item for each item in an unordered list.
When using the US keyboard, a bullet point character can be produced by pressing 7 on the numpad while keeping Alt pressed.
When using the US keyboard, a bullet point character can be produced by pressing 8 while keeping Option(Alt) pressed.
To create bulleted list items for a document, the markup language LaTeX provides the item tag <nowiki>\item </nowiki>. Each item tag inside an itemized list will generate one bulleted list item.[5]
A list item on a wiki page is indicated using one or more leading asterisks in wiki markup as well as in many other wikis.[6]
The bullet is often used for separating menu items, usually in the footer menu. It is common, for example, to see it in latest website designs and in many WordPress themes. It is also used by text editors, like Microsoft Word, to create lists.
