Keyboard shortcut for web search

ctrl+Shift+f (or other…) to web search a selection. Like ctr+f to find other occurrences on the page. instead of right-clicking and then selecting web search…

Or maybe for definition and some context… a little box with the first result of a web search appears, for a word or concept the definition is often there, the user can click to see more on a new tab or just click beside it and keep reading… (A bit as Wikipedia does… )

I found myself trying to do that the other day and thought it could be a nice and useful feature…
