Kind of annoying presentation style quirk: but some slides are on a vertical stack which you can access by hitting the down arrow instead of going right. You can tell in the bottom right which directions are available from the slide you're on.

You know, maybe it was optimized for the guy presenting it? :P

I just used the mouse wheel and it always went the right order, even if vertical.

Same, but it still seems unintuitive and pointless. Why not just keep them going from left to right? I'm pretty sure the target audience for this only really cares about the content and anything else just gets in the way.

"You are in a maze of twisty little passages, all alike."

Probably to provide the possibility of not drilling down into details so you can change the presentation based on the audience.

Personally I use it to map my presentation into chapters. It allows me to better know where I'm at while presenting, and allows people reading my slides to get an idea of how it's laid out inside my brain.

It was just used by a colleague to organise his slides into:

Topic ▼ Code example ▼ What that code renders into

The last slide was actually rendered live from the slide before it. Absolutely badass.

I really liked the presentation of slides, and enjoyed using the arrow keys to navigate. It was fun, and could have been very boring (for me).. it made me read more than I would have.. It was good viewing those slides in isolation, made me study some of the functions with more focus.

if you hit the space bar you can see a "map"; space again to return to where you were.
