I'm not, but I've strongly considered the neo layout. I have a friend who uses the eurokb layout. He's a huge fan of it. His interest is primarily in natural language symbols. Mine is primarily mathematical symbols. These days, I have a ton of substitutions defined in Google Docs (e.g. I type "zz" and get ℤ). It's not optimal, but it's easier than switching layouts. While you're remapping, I highly recommend swapping ctrl and capslock. The capslock position is far superior for the much more common ctrl. They were historically that way, but were swapped when some nitwit decided keys should be symmetrical. I remapped ctrl because I use emacs; but even for normal use, it's a substantial improvement.Anyone (ANSI or ISO) using an alternative keyboard layout?
