That is to say that on all terminal types that I'm aware of, the ENTER key is encoded as Control-M, or 13. Since they are the same key, there's no way in any terminal to differentiate between pressing control-M and the enter key. I guess this limitation has been with us so long that people did other things. In unix terminal apps, often the meta key is used as a modifier. This is usually the "Alt" key. If you need to differentiate between ENTER and control-M specifically, you'll have to build a GUI app instead. One that won't be able to run remotely over a tty stream. I know you want your apps to be exactly the same across platforms, but that's not always possible, nor always desirable. For example, on Macs, control-key is not normally used, but rather the Command-key (the apple key) which happens to be where the Alt key is on our PC keyboards. -- https://mail.python.org/mailman/listinfo/python-list
