Just got DN yesterday so I'm a newbie here. Mom is partially sighted so she's having a problem with the remote. Is there a big button remote that would work? Only need a limited amount of channels so even a channel up & down would work. But need an easy way to get to the point where it would work. The amount of useless and uninteresting channels are frustrating. It would be nice to just turn on the TV and just scroll up and down 20 or so channels. Thank you for reading, George
