I have "Look up & data detectors" set to three-finger tap in the Trackpad preference pane. This means that when I three-finger tap on a word, I get a dictionary tooltip/overlay like so:
This is something I use and want. However, there is also something I don't want. When I three-finger tap on something other than a word, like the blank background of a page, or a nonselectable word, Dictionary.app opens, like so:
Bizarrely, this Dictionary.app happens in Google Chrome, but not Preview or Finder, where three-finger tapping on a background does nothing, as expected.
Is there a way to keep the dictionary lookup tooltips for words, but get rid of the Dictionary.app opening for non-words?
