Is it possible to tag/reffer to a task in the chat or the description ?
For example, in Notion I do @nameofthetask to display the direct link of the task.
Thank you !
PS : Can someone tell me how works this option please ?
Yep, Ivann! You can mention/reference another Height task by typing the Task ID in the chat/description. Every task in Height has its own unique Task ID (T-xxx) – entering that ID in another task’s chat will post an unfurl and entering that ID in another tasks’s description will post a clickable link to the task.
(P.S. that feature is for showing task names in linked task attributes like Blocking. As shown in the 2 screenshots below, when you have that feature enabled, it’ll show the actual task name next to the task ID, but when disabled, only the task ID will be shown.)
Hope this helps!
I see, thank you for your help 
Very welcome!
