You select it from the drop down menu by its ID number when you e.g. choose set move route. It doesn't matter what you call the event (in the name box, top left of the event), the engine goes by number ID, which you can see just above that, right at the top.
It helps to give names to events so that you can identify them more easily, but that's the only function names have.
As for teleport, only players can teleport, events can't, so could you be a bit more explicit about what you want with that.
