Still can't open console in CS:GO

I’ve tried enable console, ~, bind x toggleconsole, bind x showconsole, -console, and switching the digital layout of my European keyboard. None work.
I get the console on in the main menu, but it closes when leaving menu, with no return.

If I don’t get this sorted out quick, I can’t finish my map for the Gamebanana contest, because I can’t build cubemaps or navigation points!

That’s normal that the console won’t open once it got closed. Try making a really tiny map that gets loaded when you launch csgo so you can open the console again after closing it without loosing too much time.

Ok I actually figured it out by myself after messing around a little.

Solution:

Go to the HELP & OPTIONS > MOUSE / KEYBOARD

At the very bottom of the BINDING list, you can select which key is used to open the console.

I wish the other games had this.
