I'd just finished reading and commenting on a thread, and while key pressing, mouse moving, etc, I suddenly found I was on page Preparing the UK Electricity Network for Rising Cooling Demand which says I've muted the thread some how.
How to unmute a thread?
How to determine which other threads I may have accidentally muted and not noticed?
How/Why/What key press, caused the muting to happen in the first place? I also use Thunderbird which, if in focus, uses regular ascii key presses, terminal style, as direct command, such as Next unread, Forward, Back, etc. I may have typed such a character before I'd acquired focus (i.e.. flipping between the email notifications, and the web display of the Read and reply online link. Whatever the reason. I'm now stuck without notifications on a thread I was commenting on, and the hrlp didn't help.
