How do I change the action for Force Click on a Force Touch trackpad?

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.
