After switching to Dvorak many years ago, I picked up the habits for a lot of shell commands to shift my right over two keys, so that my ring finger could hit the hyphen. `ls -l` is much more comfortable to type with middle-ring-middle than pinky-ring-pinky. I'm sure I've picked up other subtle shifts like that as well, and switching to a split layout keyboard also showed me just how much my hands crossed over for F, Y, and X.
