Oh, I think it's quite easy.

The application just has to calculate the karma of the key (some sort of hash algorithm) and if it is too low it means it can't be legal.

Maybe like the FavoriteFiles/Folders button: you press the button and a list opens where you can select the Toolbar. The management of the entries could work like it does in "List Management" now.

A similar button would also be great for the coming "Catalog switching".
