Computer Encoding and Keyboard Entry
The standard circular bullet symbol (•) is at Unicode code point U+2022. As an HTML entity, it may be entered as •, •, or • Unicode also defines a U+2023 ‣ triangular bullet, a U+25E6 ◦ white bullet, a U+2043 ⁃ hyphen bullet, as well as a U+2219 ∙ bullet operator for use in mathematical notation primarily as a dot product instead of interpunct. However, semantics normally requires that bulleted items be achieved with the appropriate use of the tag inside an unordered list (). Such lists may be denoted with leading asterisks in Wikipedia markup as well as in many other wikis.
In the Windows-1252 and several other Windows code pages, the standard circular bullet character is at 149 (decimal). To input this Alt code in Windows, press and hold Alt+0149 on the numeric keypad). The bullet symbol is also generated by Alt+7 in GUI applications, but Alt+7 in a Windows text interface (such as a Win32 console application) it generates ␇ (the bell character). Also, it can be confused with bullet symbol in code page 437 and other OEM code pages (see #In historical systems section).
On Mac OS X, pressing ⌥ Opt+8 inserts a bullet, while pressing ⇧ Shift+⌥ Opt+9 inserts the similar interpunct (·).
GTK+ applications on Linux support the ISO 14755-conformant hex Unicode input system; hold Ctrl+⇧ Shift while tapping U, then type 2022 and press ↵ Enter to insert a • or hold Ctrl+⇧ Shift while tapping U, then type B7 and press ↵ Enter to insert a midpoint.

Famous quotes containing the words computer and/or entry:
“What, then, is the basic difference between today’s computer and an intelligent being? It is that the computer can be made to see but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of pattern—a capacity essential to perception and intelligence.”
—Rudolf Arnheim (b. 1904)
“All mothers need instruction, nurturing, and an understanding mentor after the birth of a baby, but in this age of fast foods, fast tracks, and fast lanes, it doesn’t always happen. While we live in a society that provides recognition for just about every life event—from baptisms to bar mitzvahs, from wedding vows to funeral rites—the entry into parenting seems to be a solo flight, with nothing and no one to mark formally the new mom’s entry into motherhood.”
—Sally Placksin (20th century)
