OK that almost works. I say almost. 

First it started working so I can get the uncanny skills. But then I have tried to evaluated:

(global-set-key [super-key ?\a] 'tetris)

And that one does not work. 

I have also discovered that it does not act as true modifier, it acts rather as a key after key. So I cannot press Super and hold it pressed to invoke other key. In fact I have to press Super and then release it to press the other key for the function to start working.

Do you know why I cannot invoke tetris? Not that I need tetris, I would like to use my business management in console too by using the Super key. Of course I can replace the prefix with something else, but I still explore that possibility of using Super in the console. 

It would also release or liberate many keys for Emacs in console. You are doing good progress.

Now:

- why tetris does not work?

- can we make it a true modifier, even if we replace its underlying meaning to something else?

Then we can invoke a function that can detect if Emacs is running in console and that function can replace the prefix and modify it to something similar as you have proposed.

In GUI there would be no need for modification.
