Since it doesn't seem possible start the audio file directly, I have changed the shortcut to this as the next best thing:
[shortcut]
type: browse
data: /Rehearsal/
name: Rehearsal
icon: -1
talkclip:
It opens the folder then another click starts the audio file. But the shortcut display looks like this:
Rehearsal/ (/Rehearsal/)
Why doesn't the shortcut screen look like this?
Rehearsal
