Kudos on an outstanding and useful website!

I'm getting ready to use some advanced codes on the www.starbase314 website to finish the programming of my RS 15-1994, but I'm confused about some of the data. Specifically, on some devices (e.g., Panasonic DVD, device 0490) there's a section with basically three columns: the advanced code, a "DESCRIPTION" in capital letters, and a "description" in lower case letters. What do these represent? The confusion comes when there are three separate "DESCRIPTIONS" for the same advanced code and "description". And sometimes even the "description"s vary.

For example, for advanced code 702 on the Panasonic DVD (device 0490), the following is listed:

702 DOWN............Menu Down
702 MUTE............Menu Down
702 VOLUME DOWN.....Menu Down
702 MUTE............Volume Down
702 DOWN............Volume Down
702 VOLUME DOWN.....Volume Down

When I assign this code (702) to a button, what will happen? What's the difference between the "DESCRIPTION" and the "description?" I've scoured these forums (fora?) for some explanation, alas to no avail. Any ideas?

Thanks
