Using attributes/abilities to direct player to specific handout

So I've been using the attributes field with the following code to direct players to my own content created on google drive to substitute for handouts  &{template:default} {{name=@{selected|token_name}}} {{name](@{selected|bar2|max})}} Using this code I can paste a URL in the second bar of a map pin token on the world map or an encounter map to give them a pop up in chat which will link to the google drive content in order to flesh out the world and things in dungeons for them to explore on their own. My question is if this can be altered to instead reference a handout in roll20 and how exactly I would alter the code to do that as I've tried inserting brackets and referencing a handout instead with no success.

I figured out that I can accomplish this by creating a codex (a handout that references other handouts) and right-clicking the links within the codex to copy the link addresses and past them within the token reference map reference as I was doing for the google drive links. Now I just need to see if I can do this for character sheets.    Looking through the forums trying to research this question this is what I found /w gm &{template:npcaction} {{rname=Game Menu}} {{description=[Weapons](URL1) [History](URL2) [Orcs](URL3)}}

Yes I can. 

Hmmm, now I wonder if I can add some kind of history, religion or arcana check to my handout so depending on the roll they get different links to more information.
