I'm on Audacity 2.1.2 on the Mac - I can't seem to enable 'pinned playback' as described under 'pinned head playing' here: http://manual.audacityteam.org/man/playing_and_recording.html
I don't have the green downward-pointing triangle on my timeline, nor does the option appear in the Preferences > Tracks.
Am I missing something?
