[Gimp-user] how to cut both the inside and outside of an image

[chants <forums gimpusers com>]

Hi

I am trying to cut and paste an image if a ring ...there is an inner edge and
an outer edge.. and obviously the part in the middle should be cut away... I
have tried to do this, but when i click enter , the dancing ants dont appear

1. How do i move from the outside to the inside without cutting accross the ring
2. How do i do this task
3 How do i switch the scissor tool off, since it transfers to the new layer
4.In general , how do you switch the tools off

Thanks
