You know when you are editting a document in the manager and there’s the "Summary (introtext)" form field ?
Well if that had said "Summary [*introtext*]" it would have saved this n00b about fifteen minutes of searching around the documentation trying to find the correct way to get "[*summary*]" to show up in the content field.
... but in all seriousness, maybe it would be handy to have the correct syntax for ModX tags appearring with the Javascript pop-ups you get when clicking on the question marks next to the form fields of the document editor in the manager.
For example, clicking on the question mark next to the "Title" form field would bring up a pop-up....
Type in the name/title of the document here. Try to avoid using backslashes in the name!
ModX tag syntax: [*pagetitle*]
