Floyd,
It sounds to me like you haven't messed around with the Chirp software enough. Click and right click everywhere. You can't break anything. Chirp is set up similar to a spread sheet program like Excel, only with preset values for the columns and rows.
In Chirp, you can highlight a location by clicking, then right clicking to copy. Then you can right click a another location and you have pasting options.
If you are doing a lot of editing it's better to export to a CSV file. But you need to know how to work spreadsheets a little.
I have my radio almost figured out. Having a few problems understanding the Squelch Tail settings for repeaters, but I'll get it.
