Maybe I'm in the wrong thread but got here by way of Google and it's the closest I've found to an answer for my issue. I have a UR5U-8780L-TWC remote and an Element ELEFW504 tv. I have to use the select key to CHOOSE the input while using channel keys to navigate the Video Source menu. (Already finally got the channel keys to work in tv mode) So I'm trying to figure out how to get the select key to work in tv mode now. Checked the link in the previous forum post and was unable to find my specific remote. That makes me think I may be posting in the wrong place but really hope someone will be nice enough to help me out.
