shortcuts combinaison

Hello
I worked for few months with C4d and I found very usefull to combine shortcuts.
I explain myself :
It would be cool to assign for eg. "E" for edges operations and other keys for specifics operations.
I means "E" and "C" edge connect, "E" and "S" edge split, "E" and "B" edge bridge.
And why not "E" and "E" and "O" for Edge extrude option.
(you tape "E" "E" and "O" on the keyboard)
Hope somebody find this usefull and can make it !!!! :-)))
