## Notes
- Current keyboard handling is `Ctrl`-based in code paths (including on macOS builds).
- Some actions are context-dependent (current view/tool/selection state).
- The `Q` / `H` / `G` piano shortcuts act on the current piano-roll note selection.
- In pitch-correction view, undo/redo applies to the local correction editor instead of global engine history until you leave the view or press `Apply`.
- Audio clip stretching is only available when the `rubberband` executable can be found on `PATH`.
- The main editor zoom is geometric rather than linear, so equal slider movement produces equal zoom-ratio changes.
- `Group` is only enabled when the current selection contains two or more non-group clips from the same track and clip type.
- `Split` is blocked for grouped clips; ungroup first.
- Per-clip plugin graphs are audio-only and are currently built for Unix non-macOS code paths.
