Where can I find a list of Rails error messages keys?

Question

I'm trying to customize my error messages by modifying en.yml.

en:
  errors:
    messages:
      blank: "This is a required field."

And now, every empty field that has the validates presence: true validator shows this new message.

I want to find a list of messages types to modify. For example, how can I customize the numericality validator message? Or the greater_than validator?

Any suggestions where to find this?
