List of evil ex commands?

[Kendall Shaw]

I know there is an evil list but I've tried twice and had not response 
when trying to join.

In vi/vim, to find a file I type :ex. In evil this quits emacs. So, do 
people use C-z C-x C-f to find a file? I'm using helm, so for me it is 
C-z C-x C-f C-k ./ to find a file...

Do you know where I can find a list of ex commands in evil. I didn't 
immediately find it looking at evil-ex.el.
