Question about the thread icon black dots...

[Williamos]

forumdisplay.php puts icons to the left of each thread:

closed envelopes
open envelopes
bulging to indicate hot
lock to indicate closed

What does the black dot on these icons mean exactly? And where would I look for this information?

Thanks for your help!
William
