CloseReview for Look Up in Dictionary by geotibl
Rated 5 out of 5 stars
I use this all the time. I've found it more reliable that using the three finger gesture on the mac, which sometimes selects the incorrect word or doesn't work. Also easier to used that control-commmand-d. Further, it calls the full dictionary, and not the popup. I hope it's updated for Quantum!
