@The_Ad: There is already a shortcut for highlighting ctrl+h. As for disabling the popup bar, am not really keen, its designed to stay off the current line so should not interfere with reading. And adding a preference for it would require creating a whole new section in preferences, which is something I'd rather avoid for just one preference.

EDIT: And I should add that if it becomes necessary to add more preferences in the future I will be happy to add one to turn off the bar.
