I find touch typing to be most valuable to me in pair programming with coworkers, or live programming for teaching. I don’t need to think about what my fingers are doing, and I can focus on what I’m speaking or what I’m going to do/talk about next. This reduces the frequency and duration of pauses, and makes the presentations more engaging. The goal is to be modifying text just a bit slower than people can keep up with, and taking explanatory pauses after dense changes. Obviously helps if you can navigate your editor sans mouse.
