I've got a a bell expressvu 5100 (similar to the Dish 501) It has a search button which takes you to an on screen keyboard - at which point you could use your arrow keys to type a name of a program to search for. What I would like to do with my pronto pro is use the keyboard in the files section to type what program I want to search for. The numbers on the remote have three letters under each one (like on a telephone) is there any way to do this?
