The contributed module Link allows a Drupal 7 site builder to display a link in plain text. The text displayed is the link's title when there is one, or the link's URL if there is none.
This is a companion to the Drupal 8 version of the Prepopulate module, although technically you can pre-fill the field values any other way you choose and this module can still work with them.
Create additional paths for a given entity type and choose which view mode should be used for rendering. For instance, if you want to show the teaser of a node at a specific URL.
This is a very simple formatter for any Entity Reference field which allows you to render it as a link which opens the referenced entity in a jQuery UI modal (utilizing Drupal Core's libraries).
