Hi there Granny. Sounds like you may have entered the "service search" mode. Below are the applicable steps to take from the easier to read manual edited slightly by me to fit your situation:
To Edit a Service Search, press MENU. Scroll to 'Search for...' and press E/●.
Scroll to 'Edit Service' and press E/●.
Scroll to the service search you want to edit (News) and press E/●.
