That doesn't explain exactly what you are trying to do. You can copy the text from a spell and paste that into chat. Or you can cast a spell and the effects and/or description will appear in chat. If you are asking, "Can I search for a spell in the compendium and click something to send it from there directly into chat", no that 's not possible. You also can't open the compendium page for a spell and press "Show to Players", since that only works with characters and handouts. You could open the compendium page and right click on the spell name in its table of contents (probably item 2) and copy the URL. That could be pasted into chat and players could click on it to open the compendium page in their own browsers. It will even show up in the same window as if they had clicked the compendium entry itself. For instance, the URL for fireball is <a href="https://app.roll20.net/compendium/dnd5e/Spells%3AFireball?sharedCompendium=4927432#toc_2" rel="nofollow">https://app.roll20.net/compendium/dnd5e/Spells%3AFireball?sharedCompendium=4927432#toc_2</a> That same URL will work inside or outside of game.
