Pressing the shortcut while a transcript was being transcribed or cleaned up
did nothing, and the thought you had while waiting was lost. The microphone is
free the moment a recording stops, so the next dictation can now be spoken at
once; the pipeline queues it and each one is finished, pasted and reported in
the order it was spoken. The corner indicator stays with the recording under
way rather than being wiped by the previous run's progress, and a stop that
lands behind an unfinished run says it is waiting its turn.
