Since time immemorial, the way to go forward in such pages is to press the left and right arrow buttons.

This has worked in 99.9999% of presentations uploaded on the internet and posted on HN.

It's also very intuitive to try, since this is how it is in any presentation desktop app too.

"Time immemorial"? Damn, I remember pretty clearly what life was like before Web 2.0, and I'm still in my 20s. The first time I encountered one of these presentations I was confused as hell, at least this one has the decency to put arrows to click in the bottom right corner, a lot of presentations don't.

Well, I'm in my late thirties, and "before web 2.0" is "time immemorial" in tech years.

Yeah, but that should have been like 5-10 years ago. How come people still don't get them?

Heck I was confused as hell when I first encountered DOS, mice, GUIs, UNIX, browsers, etc back in the day. But we learn and move on. What puzzles me is that HN is not full of "average users" but devs and technies, and also the fact that such presentations are posted tons of times a month, and yet someone still asks...

(Sure, I can understand that this could imply a "fundamental non intuitiveness" of such UI, but whether it's intuitive or not when we first meet it, it should be second nature by now.

I believe in "idiom based design" over intuitiveness (which constraints us to UIs that we can understand at first glance, preventing designs that could need a little getting accustomed to, but be far more powerful in the long run).

And I'd argue it's not even that non-intutive. From games to Powerpoint, all kinds of apps use the arrow keys to navigate -- why wouldn't one at least try them?

The reason these comments keep appearing is because tech community is large & growing and each person encounters & is confused by their first presentation in this style at a different time. As much as I hate the relevant xkcd meme, it is pretty apt here: https://xkcd.com/1053/

> Mice

This isn't a good analogy because you are in control of whether you use a mouse or not. If it confuses you, you'll either stop using it or figure it out before participating on HN. OTOH you can surf the web for years without encountering one of these presentations, so it's jarring when someone else creates a web page that violates your expectation of how the web works

Because people are used to navigating the web with their mouse, not their keyboard
