I have a new MacBook Pro Retina 13 Early 2015 with the Force Touch trackpad.
It's described to have the following feature:
Click and continue to press on the trackpad to enable new capabilities, like looking up a word's definition, previewing a file in the Finder, or creating a new Calendar event when you Force click a date in the text of an email.
Generally: How can I change, tweak, tune, enhance the 'capability' of this force click?
Particularly: I'd love to have it do translation in Safari and Terminal much more frequently than I want it to do dictionary lookup.
