The LCD Button Editor is for renaming or moving the command found on each button on either side of the LCD screen on the remote. You don't NEED to do anything on this screen if you don't want to.
You'll notice that there are 4 pages on the LCD Button Editor Screen. Some, or all 4, of the pages will have commands on them that are commands for the device you loaded from the IR database. If you wish you can rename any of these commands by double clicking on the command itself, and typing in whatever you wish. Note that on the toolbar at the top of the LCD Button Editor Screen there are symbols you can add to your commands should you want to.
Or, you can rearrange the order of the commands on the pages by simply dragging and dropping the commands wherever you wish. You'll need at least one open command box in order to drag and drop, so if there is a command in every box on every page, you'll have to delete one of the commands that you can do without. If you wish, when your done rearranging the commands you can add the deleted command, and teach the button the command from the remote that came with the device.
These commands will appear on the LCD screen, after you click the "Apply" button on the LCD Button Editor Screen, and then double click on the device button on the Main page of the LCD screen.
I recommend you just practice doing this. You'll make mistakes and have to start over, but when you get things the way you like, you can save that configuration and name it whatever you wish. I have files named HT1 and HT2, HT1 is the configuration I use on the MX-700, and HT2 is where I set things up. If I wanted to try something without messing up my current configuration (HT1), I just open HT2 and experiment there. When I know what I'm doing, I close HT2, and apply what I've learned to HT1. Or I can actually copy and paste an entire device from HT2 into HT1.
Just keep fooling with it, and don't hesitate to consult the manual if you have a question. The index is at the very end of the manual. Page 23 explains the LCD Button Editor more concisely, and accurately than I can.
