Further, I'd say that if the number of events you would need to preventDefault on grows larger than selection, command, and maybe clipboard then that implies that we are not building the right APIs.

I also want to hide them - remove them from browser UI like context menus, menu bar, or other widgets like special toolbar appearing over contenteditable on iOS. This makes the situation which spec has to describe much more complex. That's why I think it's better to focus on basics (http://lists.w3.org/Archives/Public/public-webapps/2014AprJun/0918.html) than on trying to make specification for every feature that was introduced in any engine in any away.

This makes me think that we want something like a white list of editing features to enable in a given editable element or perhaps * to enable them all.

e.g. <div contenteditable="inline-style copy paste dragdrop"></div>
