twiddle

   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.
