Shortcut {{ - Available for all elements

The purpose of this feature is to allow, in the same way as via the dynamic field icon in the right-hand column of the editor, any element to be connected via the shortcut {{, which currently only brings up a small portion of the data.

This has a specific purpose: to simplify development and thus make the code cleaner.

A concrete example is cart reward, where three elements are needed to form a sentence such as:

- Element #1: Less than

- Element #2: XX €

- Element #3: before free delivery!

Thank you!
