[Pan-users] How UNmute?

[Beartooth]

        Pan gives me "> [quoted text muted]" every chance it gets. I 
don't want that.

        I went to Edit > Preferences > Shortcuts, and found "Mute quoted 
text" with a q in the box to its left. Deleting that didn't work, even 
after closing & re-opening Pan. 

        I don't see anything under "unmute", nor show. Putting an n or a 
u in the box for muting didn't work.

        What's the right way to un-mute, preferably once and for all??
