Are there other ways to view information about an org link that I
don't list below?

 - M-x org-insert-link, the prompts for link and description show the
   current values. Requires interacting with the prompts.

 - Switch to fundamental mode

 - M-x org-toggle-link-display

Are there ways to see this information live while navigating? Maybe on
the modeline, or messages?
