Navigation
Two axes, one safe key. The 2D model only kicks in when you actually have sections.
Two axes
When your deck contains at least two chapters (a chapter is opened by a
<deck-section>) and at least one of them has more than one
slide, Rikiki switches to a 2D navigation mirroring
reveal.js:
| Key | Action | Edge fallback |
|---|---|---|
| ← → | Previous / next chapter | Linear step at deck edges |
| ↑ ↓ | Walk slides inside a chapter | Crosses into next chapter linearly |
| Space PgDn | Linear next · always advances | · |
| PgUp | Linear previous | · |
| Home End | First / last slide | · |
When you don't have <deck-section> markers, all arrow
keys act linearly (the 2D model is hidden).
Overview mode
Press O to open a path-style overview: one row per chapter, sub-slides flow rightward, the current slide is highlighted. Click any thumbnail to jump there. Press Esc or O again to close.
The overview module is lazy-loaded · the JS and CSS fetch on first O. Same for the help overlay below.
Help overlay
Press ? or H for the full keyboard cheatsheet. The list adapts to whether 2D nav applies in the current deck.
URL hash
The canonical URL is #N · slide N (1-indexed, flat). You can
share #5 and the deck opens on slide 5. Inputs of the form
#chapter.slide (e.g. #2.3) are also accepted but
rewritten to the flat form so the share link stays simple.
The bottom-left hint
Rikiki shows a small keyboard cheatsheet in the bottom-left corner: it always lists ← →, O, ? · and adds ↑ ↓ automatically when 2D nav is active.
