+
+### Story 9.8: Keyboard Shortcuts Overlay
+
+As a power user,
+I want to see all available keyboard shortcuts in an overlay panel,
+So that I can learn and use shortcuts to speed up my workflow.
+
+**Acceptance Criteria:**
+
+**Given** a user is in the CalcPad editor
+**When** they press `Ctrl+/` (or `Cmd+/` on macOS)
+**Then** a modal overlay panel appears listing all keyboard shortcuts
+**And** pressing `Ctrl+/` again or pressing `Escape` dismisses the overlay
+
+**Given** the shortcuts overlay is displayed
+**When** the user views the panel
+**Then** shortcuts are grouped by category (e.g., Navigation, Editing, Formatting, Sharing)
+**And** each shortcut shows the key combination and a brief description
+
+**Given** the shortcuts overlay is open
+**When** the user clicks outside the overlay or presses Escape
+**Then** the overlay closes
+**And** focus returns to the editor at the previous cursor position
