guille is the keymapping chapter up to date to that regards. It would be good to explain better the bubble and the global binding. If you have one hour it would be good.

I don't much like this nice idea. Why? see all the (self flags: #toRemove) and such kind of annotations in Squeak. Then tend to last much longer than due.
