It would be way handy to be able to holler out "stumble"
and have it play back as a real time event-tag in the
logs, there's no way to do it with keyboard while driving.
Then you could pause and inspect the log when you
hear something you wanted to revisit.
Just a low bit rate sample of the PC mic input, would be
fine - just need it to be intelligible, not audiophile grade.
