Assigning shortcuts to mouse buttons

Right now I can use X-mouse Button Control to assign shortcuts to any of my mouse buttons. I need to be able to do so natively inside premiere pro.
These are my further recomendations:
-Assign MMB to Del. By doing that you'll be able to delete and ripple delet in the an blink of an eye. 
-Assign one of your mouse's side buttons to Add Edit Point and the other to Seletion tool. 
These assignments will make your workflow much more easier.
