Sorry for dump question, but how to use the teleportation?
I have already get that milestone, but have no idea how to teleport to other hex.
Could you please adjust the description of this milestone with some info about how to use it?

(english is not my primary language, so not fully sure if i just blind)

There are buttons in the hex core GUI. One of them is for you to teleport to that hex core. More easily, you can use a hotkey while mousing over the hex core entity itself, and that hotkey can be found or rebound in the controls settings.

Yea, not seen this button, as i mostly (at least currently) interested in using of provided traids, and not switching existing hex cores to Sink Mode, Generator Mode or some else. But by reading it once more, with comparing of text with other unlock features, yes it could be found.
So i need radars to use it... power... (fine with me :D)

And hotkey - default hotkey for Technology Tree is also "T". The message some time popped that Teleport feature is currently not accesible, when i opened/closed the tech tree was because of that. that has confused me some times. Now at least clear.

Thanks for response.
