What do all the file icons mean?

[Brickitect]

Can someone help me?  I never fully understood the file icons to the left of each topic.
Can someone explain to me what each one means?

Thanks for your time.

This is just a normal post.


This means the post has 2 pages, or it's "hot."


This means the post has 3 or more pages, or it's "very hot."


This means the post has a poll.


This means the post is locked.


This means the post is stickied.

Some icons can merge and if the folder is open then you have posted in it.
