:twiddle: n. 1. Tilde (ASCII 1111110, `~'). Also
called `squiggle', `sqiggle' (sic --- pronounced /skig'l/),
and `twaddle', but twiddle is the most common term. 2. A small
and insignificant change to a program. Usually fixes one bug and
generates several new ones (see also {shotgun debugging}).
3. vt. To change something in a small way. Bits, for example, are
often twiddled. Twiddling a switch or knob implies much less sense
of purpose than toggling or tweaking it; see {frobnicate}. To
speak of twiddling a bit connotes aimlessness, and at best doesn't
specify what you're doing to the bit; `toggling a bit' has a more
specific meaning (see {bit twiddling}, {toggle}).
