Yes, you would just hit back button, but if there are alot and you don't want to keep track of what you've read just hit the shortcut unread again and it will not show the ones you just read.
As for the list... if you just click on forums the side columns will show the threads you have been active in as well as the rest of the active.

hehehe
Do unto others as you would have them do unto you...
