Export templates can be stored in a Tinderbox note.
The note's Properties Inspector Prototype sub-tab has an check-box, Template. If this is checked, the note's path appears in the template menu, and the note may be used as an export template. (N.B. this option applies only to proper notes and not agents).
Template notes appear in selection menus by their complete path. For example, if the template Book Template is a note inside the root-level container named "Templates", it appears in the menu as
If a note's name (or path/name) is identical to the name of a template file, the note template will be used rather than the file.
To avoid unwanted name conflicts, it is suggested to store templates in a dedicated container, perhaps using a self-evident name like "Templates". When referring to a template in code, it is sufficient to use the $Name as a quoted string (assuming it is unique in the TBX).
A note's availability as a template is stored in attribute $IsTemplate.
Template notes ignore the smart links feature (i.e. don't generate RTF-based URL links).
