The default action for the left most hardkey on the TSU6000 is no longer working correctly. It was the page up/down button originally, After renaming the button and then removing the name, it no longer gives me the page up/down function unless I click in the right side device menu and select a device from there 1st. Then the label appears as does the page numbers at the top left. I can't find anyway to get the button back to the way it was originally.

What does it say in the action list? Is it aliased to something? I have a feeling you erased it's actions.

I'm a newbie, so maybe I'm not getting it. I had what I think was a very similar problem. I have an RC5200 and I accidentally deleted the functions associated with my right hard key that normally had a browser-like "ahead" function associated with it. I backed up my configuration to my PC using Touch Screen Setup, then hit revert on the 5200, which restored the original factory configuration, including the hard key function. Then, I backed up the reverted configuration to my PC under a different file name. Then I merged the two files and voila! My original configuration was restored and my hard key worked again. I was advised by Marantz that attempting to actually reprogram the hard key was possible, but required a fair bit more programming knowledge than they couold impart to me during a 5 minute phone call. Let me know how it goes.

Adam,

That is what this site is all about. Programming your remote and totally customizing it to make it do what you want. Keep reading you will get it. :) All of us thought this was Chinese when we first came here. Once you understand the software it is really easy I promise.
