We can reach some internal values using a special query name called xdg3. The syntax is as with all others ?xdg3.key=somevalue and [{ xdg3.key.subkey }].

At the moment this special key is used for sessions and to reach url parameters in the page code.

xdg3.url

This key reflects any query key set in the url. If you have /view/?fieldname1=val1&tablename.fieldname2=val2 you can reach this by livetext in the page using the syntax [{ xdg3.url.fieldname1 }] and [{ xdg3.url.tablename.fieldname2 }].
