Fixed notebook forms are similar to fixed dynamic paragraph forms and use values that are hard-coded in the code.

The structure for the notebook form is $${<notebook-name>}. It is similar to Create Fixed Dynamic Forms, except that it uses the escape character ($) twice. For example:

%md
This contains a $${notebook-form}.

This will show a notebook form as shown:

In case there is a need to use the fixed notebook form syntax in a paragraph's code without creating forms, then that can be achieved by preceding $$ with a backslash \. For instance, \$${name} syntax will not create a form and will be parsed as $${name} in paragraph results.

If the escape functionality of the backslash \ is undesirable, then that itself can be escaped with another backslash \ (\\$${name}).
