Ever since Lion I've been using Better Touch Tool in order to have the three finger tap gesture trigger a middle click. Now, in Mountain Lion, Apple has changed the in-line dictionary definition gesture from three finger double tap to three finger tap. I am finding that sometimes I get middle click and sometimes I get a dictionary definition. How can I disable Apple's dictionary definition gesture?

Edit: sometimes I am getting both a middle click and a dictionary definition.

  • Disabling "Look up" feature disables Three-finger-tap gesture in Better Touch Tool - have you found any workaround? Oct 2, 2012 at 10:03
  • Yeah, I just kept three finger tap as lookup and made three finger click to be middle click. It takes some getting used to but its bearable.
