ok i just looked up the hungarian keyboard layout.
does numpad 0 or 0 at the top numbers do it? skyrim wiki says that opens the console with hungarian keyboard for skyrim, which uses the same character.
you can't make a final build of your game for your players to play that allows for cheats. it only works with the test executable, so i wouldn't stress if you can't get it to work. you are not really missing much.
Thank you all for your help! I added "-console /" to the game shortcut properties and with AltGr + Ö I was able to bring up the console and enter the cheat codes. Wouldn't have thought it would work in a similar way to Half-life. :D
