"Translate selected text shortcuts" don't work, nothing happens (and besides that, not all shortcuts are possible, e.g. you can't have alt + alt or ctrl + ctrl like other extensions do, you must always include a letter). Translation on selection with options to customise behaviour is brilliant, but a translation of the whole paragraph upon mouseover (controlled by keyboard shortcuts) would be much better. Selecting text on many news sites is very tricky, and makes the use of this extension awkward.
