In addition to the other points above, i have found that in some workflows I have found that using talon and cursorless i am faster than I was using just a keyboard and mouse. I have had some bad RSI flare ups over the past few years and they have been a lifesaver getting me though my undergrad and most of my masters. Even during the times in-between flare ups i found that using them to editing a latex document was much more convenient being able to reference paragraphs/sentences/words and then change them or move them around.
