[Question] commands

you remember how in NZP beta you could type a letter, then press tab on the console, it'd show you a list of commands that start with that letter? is there something like that on the demo or unofficial patch? i wanna learn the commands this game has, and i wanna see some different visual effects like motion blur. i the beta i usually play around with the commands there too. and i kinda wanna do that on the demo/unofficial patch too.
so once again, is there a way to see a list of commands the same way you do it on NZP beta with the tab button?
