Press number 5 and go to a channel starting with a "J"

I have one small question. When I go to all channels, and for example I want to go to a channel starting with a "J" , is there a way to press number 5 and go there?

Just tried it with black hole image. No, it doesnt work. I think I am going to go back to openvix again. :(
