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 knobs 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). 4. Uncommon name for the twirling baton
prompt.
