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.

  • Is there any way to remove the shortcut associated with looking up words? I went to System Preferences > Keyboard > Shortcuts, and then clicked on services in the menu on the left. There is a shortcut labeled Look Up in Dictionary. However, this opens the word in the Dictionary app instead of the Look Up window. How do I remove the ⌃⌘D keyboard shortcut? @grg♦ – Peter Schorn Dec 13 '19 at 4:34
