Creating templates for events - how to do it?

How to create templates for events, for these ones, for example:
events.png

When I selected these events and clicked on “Create template” I typed “MyObject” and “Name of the object” in parameters but whatever name I type in the object field it doesn’t change in the inserted events.

How to edit/delete user’s templates?
Wanted to delete some which I created but couldn’t see them in the Template folder. I see there only 3 templates which came with GD. When I’m saving my new template I can see my previous ones with a lock sign on them and can delete them only there by right clicking on the name of the template and choosing “delete”.
