Tutorial: Radius node output port?

[Gurkenglas]

During the tutorial, I encounter:

There is no explanation what an output port is and clicking around near and at the flashing area (the rounded orange square) does not do anything. After clicking Next to continue:

The new node has disappeared, a line from the radius (output port, I suppose) follows the cursor, and it's still telling me to Please wait... as I type this.

Duplicated https://github.com/luna/luna-studio/issues/737, also wrong repo.
I see you've opened many issues for Luna Studio and not the Luna Compiler. Do you know if you can move them?

There is a "move issue" button on the right. We try to move issues around, however, the author is also allowed to do so!

@ricardopieper thank you for your help! Closing it as duplicate.

I see no such button:

Sorry for the misreporting and feel free to move them.

Oh! I just realized it is a ZenHub feature, not built into GitHub. We use ZenHub internally, if you want, you can install free Chrome plugin or create online ZenHub account and you will get the button on the right below 1 participant message !
