mode
n. A general state, usually used with an adjective
describing the state. Use of the word `mode' rather than
`state' implies that the state is extended over time, and
probably also that some activity characteristic of that state is
being carried out. "No time to hack; I'm in thesis mode." In its
jargon sense, `mode' is most often attributed to people, though
it is sometimes applied to programs and inanimate objects. In
particular, see
hack mode,
day mode,
night mode,
demo mode,
fireworks mode, and
yoyo mode; also
talk mode.
One also often hears the verbs `enable' and `disable' used in
connection with jargon modes. Thus, for example, a sillier way of
saying "I'm going to crash" is "I'm going to enable crash mode
now". One might also hear a request to "disable flame mode,
please".
In a usage much closer to techspeak, a mode is a special state
which certain user interfaces must pass into in order to perform
certain functions. For example, in order to insert characters into a
document in the UNIX editor `vi', one must type the "i" key,
which invokes the "Insert" command. The effect of this command
is to put vi into "insert mode", in which typing the "i" key
has a quite different effect (to wit, it inserts an "i" into the
document). One must then hit another special key, "ESC", in
order to leave "insert mode". Nowadays, moded interfaces are
generally considered
losing, but survive in quite a few
widely-used tools built in less enlightened times.
