If I want to know the peak voltage I leave the meter connected go off

called up,
(depending on meter) without me having to sit there for seconds,
minutes, hours or days staring at a needle with a mirror behind it.

Slight misunderstanding here. I'm talking of the kind of tweaking and
peaking us radio hams have to do when tuning intermediate frequency
stages of amplifiers. The effect is much more easily seen with an
analogue meter.

You can "amplify" the trace and then move it with the shift controls to
magnify it as it were...
