For scroll wm, By creating a widget

### Alternatives/Existing Solutions

No existing solution

The issue names no files, tests, or entry points and does not identify what “scroll wm” means beyond a widget request. Start by clarifying the target compositor and locating the existing widget and compositor-integration code; done would be a visible current-mode widget for the selected compositor.
