DuckDuckGoThe timeline zooms with the scroll wheel in the keyframe area and scrolls with Shift+scroll. Most "unresponsive timeline" reports are a view problem — the playhead or the keyframes are outside the visible range rather than missing.
If one or more of these match what you are seeing, you are on the right page.
Ordered from most to least likely. Work down the list — each cause is paired with what to do about it.
Press Ctrl+Alt+F to fit the full project duration, Ctrl+Shift+F to fit the work area, or select keyframes and press F to zoom to them.
The scroll wheel in the keyframe area zooms, centred on the cursor. Hold Shift to scroll horizontally instead, or drag the scroll bar at the bottom of the keyframe area.
Turn on the follow-playhead toggle in the transport bar so the timeline scrolls automatically to keep it visible.
Use layer search, the track type filters, and the keyframe-only filter to hide tracks that have nothing on them.
Each element row has an expand arrow revealing one track per animated property. Keyframes are on those sub-tracks, not the element row.
If none of the causes above match, contact support with the steps to reproduce the problem, your browser and version, and any message from the browser console. You can reach us at support@flashfx.app.
