I'm an avid Emacs user on all the other platforms that I use, but I can't see how it would help me on the 770 - at least, not without a keyboard, which I don't currently plan to acquire. The thing that makes Emacs so effective is its vast array of extensions combined with the fluency in using it that one accumulates from experience - but that fluency depends I think on a traditional keyboard.

Sorry that this doesn't really help, but that's what I thought when reading your post. I'd be interested to hear if others agree or disagree. - Neil
