You beat me to it.
I had an occurrence with a very experienced captain in RHS moving the flaps from 5 to 1 when I had called one to go (SOP call) missed by the PNF. He had been busy with the radio at the time and came back with an instantaneous movement of the flap lever. No hand on lever, think, then move as mentioned above. Very sound advice. I agree, no problem with rectifying the problem immediately as you mentioned.
Another good bit of advice concerns the Boeing gear lever from up to off after TO. I inadvertently from LHS moved the lever a gnats pubic past the off detent and was amazed to hear the scream from the gear doors as they opened. The ginger beers said that in future simply move the lever back to the up position as only the doors would have moved and bobs your uncle, no problems.
