Delete unused noded trees

I’m using the Animation Nodes addon and I can’t seem to figure out how to delete unused trees and there doesn’t seem to be a hotkey for it. I’ve tried going into the outliner, but there is not option to delete them. I’ve tried unlinking them by making sure the “F” next to the node tree name is un-checked. But when I save and re-open they are still there. Am I missing something?

Sorry, I know this is a little difficult to find at first,

Just hit Space over the node editor and search for “Remove Animation Node Tree”.

There are some technical reasons why you can’t simply remove AN trees like any other tree, I don’t want to go into details now…

Thank you very much. I’ll take your word for it on the explanation.

Thanks. That did it. I’ll take your word for it on the explanation.
