:alt: /awlt/ 1. n. The alt shift key on an IBM PC or {clone}. 2. n. The `clover' or `Command' key on a Macintosh; use of this term usually reveals that the speaker hacked PCs before coming to the Mac (see also {feature key}). Some Mac hackers, confusingly, reserve `alt' for the Option key. 3. n.obs. [PDP-10; often capitalized to ALT] Alternate name for the ASCII ESC character (ASCII 0011011), after the keycap labeling on some older terminals. Also `altmode' (/awlt'mohd/). This character was almost never pronounced `escape' on an ITS system, in {TECO}, or under TOPS-10 —- always alt, as in "Type alt alt to end a TECO command" or "alt-U onto the system" (for "log onto the [ITS] system"). This was probably because alt is more convenient to say than `escape', especially when followed by another alt or a character (or another alt *and* a character, for that matter).
:alt bit: /awlt bit/ [from alternate] adj. See {meta bit}.
:altmode: n. Syn. {alt} sense 3.
:Aluminum Book: [MIT] n. `Common LISP: The Language', by Guy L. Steele Jr. (Digital Press, first edition 1984, second edition 1990). Note that due to a technical screwup some printings of the second edition are actually of a color the author describes succinctly as "yucky green". See also {{book titles}}.
:amoeba: n. Humorous term for the Commodore Amiga personal computer.
:amp off: [Purdue] vt. To run in {background}. From the UNIX shell `&'
operator.
:amper: n. Common abbreviation for the name of the ampersand (`&',
ASCII 0100110) character. See {{ASCII}} for other synonyms.
:angle brackets: n. Either of the characters `<' (ASCII
0111100) and `>' (ASCII 0111110) (ASCII less-than or
greater-than signs). The {Real World} angle brackets used by
typographers are actually taller than a less-than or greater-than
sign.
See {broket}, {{ASCII}}.
:angry fruit salad: n. A bad visual-interface design that uses too
many colors. This derives, of course, from the bizarre day-glo
colors found in canned fruit salad. Too often one sees similar
effects from interface designers using color window systems such as
{X}; there is a tendency to create displays that are flashy and
attention-getting but uncomfortable for long-term use.
:annoybot: /*-noy-bot/ [IRC] n. See {robot}.
