I'm brand new with Roku, and have little computer skill.
I'm interested in finding a way to use my computer keyboard to type in song names, rather than
having to laboriously hunt-and-peck with the Roku remote. Any advice is appreciated.

BTW, I have a wired connection, not wireless.

You can use Remoku or another network remote app, such as DVPRemote for iPhone or Roku Remote for Android.

Remoku is a web app, free, and runs on modern browsers like Firefox 3+, Chrome, Internet Explorer 7+, and mobile safari on iPhones.

Wait, do you have a Roku-brand audio player(which are all discontinued), or the Roku video streaming device?
