Great add on. Please add the option to activate the wikipedia symbol with a keyboard shortcut, not every time I double click a word, as it is now. I don't always want to search wikipedia when I select some words.

It would be nice to able to activate it with a kb shortcut held-down instead of having an annoying bubble pop up all the time (I am always selecting text pointlessly while reading).
Say, hold-down [alt] and the bubble pops up, or the window.
Actually, a context menu option would also be nice.

Options are your friend.
