+Example: Enhanced 'Scroll' action with page amounts and element-specific scrolling.
+
+This script demonstrates the new enhanced scrolling capabilities:
+
+1. PAGE-LEVEL SCROLLING:
+   - Scrolling by specific page amounts using 'num_pages' parameter (0.5, 1.0, 2.0, etc.)
+   - Scrolling up or down using the 'down' parameter
+   - Uses JavaScript window.scrollBy() or smart container detection
+
+2. ELEMENT-SPECIFIC SCROLLING:
+   - NEW: Optional 'index' parameter to scroll within specific elements
+   - Perfect for dropdowns, sidebars, and custom UI components
+   - Uses direct scrollTop manipulation (no mouse events that might close dropdowns)
+   - Automatically finds scroll containers in the element hierarchy
+   - Falls back to page scrolling if no container found
+
+3. IMPLEMENTATION DETAILS:
+   - Does NOT use mouse movement or wheel events
+   - Direct DOM manipulation for precision and reliability
+   - Container-aware scrolling prevents unwanted side effects
