frobnicate
jargonprogramming
To fiddle with a setting or object, adjusting it without deep intent - classic hacker-dictionary vocabulary.
From the Jargon File, with a documented scale of intent: you frob a knob aimlessly, twiddle it with mild purpose, and tweak it with precision. Surviving in the wild mostly as 'frob', it signals fluency in the culture's oldest dialect.
Also known as: frob, twiddle
