Go forward to Frobnitz.
FROBNICATE v. To manipulate or adjust, to tweak. Derived from
FROBNITZ (q.v.). Usually abbreviated to FROB. Thus one has the saying
"to frob a frob". See TWEAK and TWIDDLE. Usage: FROB,
TWIDDLE, and TWEAK sometimes connote points along a continuum. FROB
connotes aimless manipulation; TWIDDLE connotes gross manipulation,
often a coarse search for a proper setting; TWEAK connotes
fine-tuning. If someone is turning a knob on an oscilloscope, then if
he's carefully adjusting it he is probably tweaking it; if he is just
turning it but looking at the screen he is probably twiddling it; but
if he's just doing it because turning a knob is fun, he's frobbing it.
