How do you open the console for the commands?
You use the tilde, " ` " key.
I tried, but it does not work. Is there another important factor I am missing?
It works for me in v4.9. So as far as I know, no you aren't missing anything. Pressing tilde opens a small command line in the bottom left, and you can press it again to open a larger window. Perhaps use an unused slot and try a new character?
