The Preview Shortcuts section was missing the shortcuts shipped in #710
and #811: J/K/L shuttle, I/O work-area markers with A/E jumps, the
Cmd/Ctrl+Scroll preview zoom-at-cursor, and undo/redo. The arrow-key
entries were also wrong — they step by frames, not seconds.
Reorganise the table into the same groups the in-app `⌨` panel uses
(Playback, Work area, View, Application) and source each row from
`usePlaybackKeyboard.ts`, `useAppHotkeys.ts`, and the `NLEPreview` wheel
handler so the doc tracks what the Studio actually does. Mention that
the loop respects the work area when in/out are set, per #811.
Closes#812
Fast reference for non-technical video editors and creatives — covers the
fast loop, terminal shortcuts, Studio keyboard shortcuts, CLI commands,
timing attributes, render presets, publish/share, and quick fixes.
