also, added a video that shows how the auto ratchet/spin wheel works.
xahlee.info/kbd/logitech_m…
the auto ratchet/spin actually uses a motor. that's rather lame. I'd think, there's a pure mechanical way to make it happen.

sometimes in programing language design, you know something you don't like, but can't explain it well. Only years after, you found the exact reason, able to explain it as logic, and to have short describtive phrase, that when people hear, they go ah.
A name for a thing/concept, or descriptive phrase, is very powerful. When you don't have it, you mumble and people don't buy it. When you have it, sometimes it can even help falsity. For this reason, many cults, are full of jargons, unix hacker cult, perl, scientology, sjw.
for example, popular jargon in programing include: timtowtdi (perl), KISS, DRY, unix philosophy, patterns, agile. sjw jargon includes: microagression, cis, gaslighting, safespace, intersectionality.

Visual CSS
xahlee.info/js/css_index.h…
major update.
here's 2 different web design of navigation panel. The 1 with scroll bar is better. because, if not, when doc is long, the left side is blank, and needs to scroll all the way to the top to use it.
currently, trying to solve the navigation panel problem on my site. e.g.
xahlee.info/js/js.html

1 visibility problem。only the top few links visible
2 hard to find which link in panel is the current article.
3 hard to use. needs to scroll a lot to use buried links in panel.

there are thievery pdf versions online, but all code/formula are screwed. You better buy the real thing.
