Enable keyboard shortcut to look up word in dictionary I have been using the trackpad w/ force touch to look up the defintions of words when browsing (safari/chrome/ff/etc).  It looks like this:



The problem is my wrist has been bothering me as I use the trackpad so I decided to get an ergonomic mouse (logitech mx master 2s) but now I can't seem to figure out how to mirror this 'look up word in osx dictionary' behavior. 

I looked at defaults read -g but nothing stood out.  How can I use a mouse + keyboard option to mirror this 'look up' word behavior that force currently has on my trackpad?
command ⌘control ⌃D is the built-in shortcut for this, performing a Look Up on the current mouse position, as if you'd used Force Touch.
