Bullet (typography)

Items—known as "bullet points"—may be short phrases, single sentences, or of paragraph length.^[1] Bulleted items are not usually terminated with a full stop unless they are complete sentences. In some cases, however, the style guide for a given publication may call for every item except the last one in each bulleted list to be terminated with a semicolon, and the last item with a full stop. It is correct to terminate any bullet point with a full stop if the text within that item consists of one full sentence or more. Bullet points are usually used to highlight list elements.

Take for example this arbitrarily chosen statement "Bullets are most often used in technical writing, reference works, notes, and presentations". This statement may be presented using bullets or other techniques:

• Technical writing
• Reference works
• Notes
• Presentations

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 1234 5678 9876 4321 might be displayed as •••• •••• •••• 4321.

A variant, the bullet operator (U+2219 ∙ BULLET OPERATOR) has a unicode code-point but its purpose does not appear to be documented.^[a] The glyph was transposed into Unicode from the original IBM PC character set, Code page 437, where it had the code-point F9₁₆ (249₁₀).^[2]

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:

• U+2022 • BULLET (•, •)
• U+2023 ‣ TRIANGULAR BULLET
• U+2043 ⁃ HYPHEN BULLET (⁃)
• U+204C ⁌ BLACK LEFTWARDS BULLET
• U+204D ⁍ BLACK RIGHTWARDS BULLET
• U+2219 ∙ BULLET OPERATOR for use in mathematical notation primarily as a dot product instead of interpunct.
• U+25CB ○ WHITE CIRCLE (○)
• U+25CF ● BLACK CIRCLE
• U+25D8 ◘ INVERSE BULLET
• U+25E6 ◦ WHITE BULLET
• U+2619 ☙ REVERSED ROTATED FLORAL HEART BULLET; see Fleuron (typography)
• U+2765 ❥ ROTATED HEAVY BLACK HEART BULLET
• U+2767 ❧ ROTATED FLORAL HEART BULLET; see Fleuron (typography)
• U+29BE ⦾ CIRCLED WHITE BULLET (⦾)
• U+29BF ⦿ CIRCLED BULLET (⦿)
• U+25C9 ◉ FISHEYE used in Japan as a bullet, and called tainome.

To create bulleted list items for a web page, the markup language HTML provides the list tag <li>. 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 \item . Each item tag inside an itemized list will generate one bulleted list item.^[3]

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.^[4]

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.
