Even with CLI tools, you rarely spend most of your time typing, but rather looking at the output. Knowing how to modify and rerun previous commands is far more important for CLI fluency than typing speed. (things like ^r, !!, !*, etc...) In fact, I have noticed that my default hand posistion has shifted to placing my left hand on the bottom left corner of the keyboard (thumb on logo-key, pinky on shift), because that is where I need it for shortcuts. Sometimes I shift to a normal typing stance (such as making this comment), when I actually need to bang out a large amount of text, but that is the minority of what I need to do when programming.
