Hi Avocadocommader,

I just stumbled over this:

How to write a template

As mentioned, in a template, use the {$f_id} syntax to insert the value of fieldId=id.
It is also possible to insert the ItemId itself, which is usefull to create new wiki pages with tracker plugins inside. To do this you'll have to add an Auto-Increment Field to your tracker, with the appropriate options to auto-fill it with the itemId. This new field content (itemId value) can then be inserted in the template with the syntax seen above.
