Thanks for the feedback. :-) :w is mentioned as a footnote because :up is more sensible in the general case, as it preserves file timestamps and saves needless disk access, the latter being particularly useful when dealing with larger buffers or working over a slow link. If somebody wants a quick answer to the question, they can just look at the Solution. If they want to understand how saving works, and its how it relates to existing mental models they have of text editors, the Discussion elaborates. This is in contrast to the "cheatsheet" approach, which does exactly what you suggest. It gives a single cryptic command, then moves on to the next example. This may be sufficient for you and I, but newer users would prefer a more cohesive explanation. Oh, and the "Needless Comment Form" was added after multiple readers requested it. Apparently people find it easier than cloning the Git repository and submitting a patch. ;-)
