The glasses can’t press keys on your computer by themselves — so this needs a small Bridge page open on the machine running your slides.
- On that computer, open
herald.ascents.gg/a/slides/bridge
- Enter your pairing code (shown on the home screen).
- Keep that tab open next to your slideshow.
The bridge turns each press into a real key — Page Down / Up, B, Home/End — for browser-based decks (Google Slides, reveal.js, a PDF in the browser), and shows a big NEXT / PREV cue as a universal fallback.
A browser can’t inject keys into native apps — that’s an OS limit, not a bug. For Keynote/PowerPoint desktop, use the on-screen cue, or present from the browser.
