+# Design Specification: Keyboard-Driven Row Selection & Range-Copy for the Ledger
+
+**Issue**: RevoraOrg/Revora-Frontend#466
+**Type**: UI/UX Design | **Status**: Specification
+**Designer**: @laurentketterle-hub (Stellar Wave 7th Wave)
+
+## 1. Overview
+
+The Ledger is the most data-dense surface in Revora. Currently mouse-only for selection and copying — inaccessible for keyboard users and inefficient for power users extracting data for reporting/accounting/tax.
+
+This design adds keyboard-driven row navigation with single/range selection and range-copy (TSV, CSV, JSON) to the virtualized Ledger.
+
+## 2. Interaction Model
+
+### Keyboard Shortcuts
+| Shortcut | Action |
+|----------|--------|
+| ↑/↓ | Move focus up/down one row |
+| Shift+↑/↓ | Extend selection range |
+| Space | Toggle selection of focused row |
+| Ctrl+A | Select all visible rows |
+| Ctrl+Shift+A | Select all rows (including off-screen) |
+| Ctrl+C | Copy selected rows (tab-separated, Excel-pasteable) |
+| Ctrl+Shift+C | Copy with headers + format dialog |
+| Escape | Clear selection |
+| Page Up/Down | Move focus by visible page |
+| Home/End | First/last row |
+| ? | Keyboard shortcuts overlay |
+
+### Mouse (Enhanced)
+Click: select single row. Ctrl+Click: toggle. Shift+Click: range. Right-click: context menu with Copy, Copy CSV, Copy JSON, Export. Drag: multi-select range.
+
+## 3. Selection Visual Design
+
+**Normal row**: transparent bg. **Focused row**: blue 3px left border. **Selected row**: blue highlight bg rgba(59,130,246,0.15). **Range selected**: all rows between anchor and cursor highlighted. Dashed connector between rows in range.
+
+### Selection Toolbar
+Floating sticky bar above Ledger when selection.count > 0: `[3 selected] [Copy] [Copy CSV ▼] [Clear]`
+
+## 4. Copy Functionality
+
+| Format | Trigger | Example |
+|--------|---------|---------|
+| Tab-separated | Ctrl+C | Excel-pasteable columns |
+| With headers | Ctrl+Shift+C → dialog | Header row + data |
+| CSV | Right-click → Copy as CSV | "id","type","amount","status" |
+| JSON | Right-click → Copy as JSON | [{"id":42,...}] |
+
+**Feedback**: Toast "✅ Copied 3 rows" slides up from bottom, auto-dismiss 2s. Selected rows flash briefly (250ms).
+
+## 5. Accessibility
+
+- role="row", aria-selected, aria-rowindex on each row
+- aria-activedescendant on table container for focus tracking
+- Screen reader: "Selected row 42. 3 rows selected." "Copied 3 rows. Tab-separated format."
+- Focus stays on last selected row after copy (no focus loss)
+- Keyboard shortcuts overlay: ? key shows modal with all shortcuts
+
+## 6. Implementation (Virtualization-Safe)
+
+Selection state: `{ anchorIndex, focusIndex, selectedIndices: Set<number>, lastCopiedFormat }`. Selection by row ID persists when rows scroll out/in. O(1) lookup via Set. 10K row cap for copy. Selection toolbar is a portal (doesn't re-trigger virtualization).
+
+## 7. Edge Cases
+
+Sort: selection persists by row ID. Filter: hidden rows deselected. New row: indices shift, IDs persist. Row deleted: silently removed. Page change: configurable (clear or persist). 10K+ rows: warning before copy.
+
+## 8. Testing Checklist (16 items)
+
+Arrow keys navigate, Shift+Arrow extends range, Space toggles, Ctrl+A selects all, Ctrl+C copies + toast, Ctrl+Shift+C shows dialog, Escape clears, selection survives sort/filter, copy to Excel preserves columns, screen reader announces, keyboard overlay works (? key), right-click context menu, drag multi-select, WCAG AA contrast, virtualization-safe, 10K+ warning.
