Something I'm not seeing in this discussion is that commands entered via keyboard are typically in English or an English mnemonic. That excludes most of the world's population. Are there command line style interfaces that are commonly used but not English based?

I don't think it excludes anyone. My native language has nothing to do with English, but I was pretty comfortable with an English-based set of keyboard shortcuts. It's just something to memorize, and that's it.
