Controls & keyboard shortcuts
Videos run automatically. When the slider starts to move the video controls will start working (controls are unresponsive while the full video loads).
Space toggles play/pause. ← and → rewind and advance 3 s. Pausing the video and using arrow keys allows convenient review.
↑ pauses and rewinds by 1 frame. ↓ pauses and advances by 1 frame. Holding either acts as fast-rewind / fast-forward.
Entering fullscreen replaces keyboard and on-screen controls with your browser’s native controls.
