There's not enough evidence to conclude whether you're refuting my points, or I'm paranoid, or we're miscommunicating again. However, the force or momentum of my argument isn't as strong as I perceived it was originally.
Your argument has the form, "I can't imagine it, therefore it isn't true," such as when you say, "doesn't seem consistent" and "simply isn't valid". However, I would be flattered and glad you want to understand.
I would guess that most readers of the forum could imagine my argument. Your seniority metric is approximately 100x mine, so my position on that matter is not strong; however you do seem to be speaking for more people than just yourself. Did I perceive the momentum of my original argument incorrectly?
mIRC scrolls differently depending if you use the mouse wheel or page key. That much is empirical although our positions differ significantly on what that means. Furthermore, that may be true of other applications, but, returning to my "information display" thread, it's less important in applications where screen space isn't quite so scarce compared to content. mIRC may even be scarce (or unique) in that regard, since the television equivalent of IRC would be a dedicated bidirectional radio feed and camera for every viewer, such that every viewer could control their camera motion, applicable to both sports and fiction; that is, investigate the scenes independently; or in other words, interactive video.
Certainly we're not unfamiliar with scrolling the paragraph we're reading off the screen in other applications; the math example is merely an example of that, something where you'd want all and only certain information on the screen at once.
Long story short, I want the mouse wheel to be changed to behave like the page key, although also accommodate long paragraphs. That might or might not be precedented, but with enough scripting API's, I could pursue it myself, and possibly be able to announce some good balance or compromise between those two constraints later.
Also, disinterested health and safety reminder to everyone to go easy on the carpal.
