Using token actions from chat with @{selected|NAME} not working

If i use @{selected|INI} like described here in the chat: <a href="https://wiki.roll20.net/Token_Actions" rel="nofollow">https://wiki.roll20.net/Token_Actions</a> it does say No attribute was found for @{selected|INI} altough the attribute exists and I can roll it from the charsheet as well as from the token action bar.

INI is a character sheet button? When you've rolled it from the character sheet, can you push the up arrow in chat and see what the command looked like?

Yes. And it shows %{Vago|INI}. But when I select the token associated with vago and use @{selected|INI} it does only show No attribute was found for @{selected|INI} GM (GM): selected|INI Edit... ok, because it is %{Vago|INI} and not @{Vago|INI} it works with %{selected|INI}. I somehow assumed i have to use @ along with selected to work. Someone might want to add this to the wiki. When creating Token Actions, you can also use the @{selected} token variables along with token actions to great effect, creating macros for system-wide rolls (e.g. Bluff) that show up when a token is selected, and pull information from the selected token to perform the roll (3.).

Wiki: <a href="https://wiki.roll20.net/Macros#Nesting_Macros" rel="nofollow">https://wiki.roll20.net/Macros#Nesting_Macros</a> It is covered in the macros section, but probably could be covered elsewhere, or at least referenced.

Oh...

@ is used for attributes, while % is used for abilities (and # is used for macros). Roll buttons are abilities.
