Hi everyone,
We are very pleased to announce that After Effects 2023 (version 23.0) adds commands for navigating between keyframes on only selected layers or properties. By default, the new commands are mapped to Shift+J and Shift+K, but you are free to remap them to shortcuts that best fit your workflow.
After Effects 2023 also adds other highly-requested improvements like Native H.264 Export, Selectable Track Mattes, new Composition Presets, and more. Full details are available here: https://helpx.adobe.com/after-effects/using/whats-new.html
