Submission guide / text parsing macros

I am wondering if FN can do "text parsing macros" in description and journals like FA.

For example:

embed YouTube videos,

show another members icon and names in Description

and <<< PREV | FIRST | NEXT >>> buttons for comic / picture series.

If yes, please add a guide and link at somewhere easy to find when uploading for easier navigation. (Such as in Manage Submissions )
