+# Input and Events
+
+McRogueFace provides keyboard, mouse, and window event handling through Python callbacks. Events are dispatched through the scene system, allowing different scenes to have different input handlers.

+
+## Keyboard Input
+
+Register a scene-level callback that fires on every key press/release:
+
+```python
+import mcrfpy
+
+def handle_key(key: str, pressed: bool):
+    """
+    key: Key name (e.g., "W", "Space", "Escape", "Up")
+    pressed: True on press, False on release
+    """
+    if key == "Escape" and pressed:
+        mcrfpy.setScene("menu")
+
+mcrfpy.keypressScene(handle_key)
+```
+
+### Key Names
+
+Common key names from SFML:
+- Letters: `"A"` through `"Z"`
+- Numbers: `"Num0"` through `"Num9"`
+- Arrows: `"Up"`, `"Down"`, `"Left"`, `"Right"`
+- Special: `"Space"`, `"Enter"`, `"Escape"`, `"Tab"`, `"LShift"`, `"RShift"`, `"LControl"`, `"RControl"`
+- Function: `"F1"` through `"F12"`
+
+---
+
+## Mouse Input
+
+### Element Event Handlers
+
+All UIDrawables support mouse event callbacks:
+
+| Property | Signature | When Called |
+|----------|-----------|-------------|
+| `on_click` | `(x, y, button) -> None` | Mouse button pressed on element |
+| `on_enter` | `() -> None` | Mouse enters element bounds |
+| `on_exit` | `() -> None` | Mouse leaves element bounds |
+| `on_move` | `(x, y) -> None` | Mouse moves within element |
+
+```python
+frame = mcrfpy.Frame(pos=(100, 100), size=(200, 50))
+
+frame.on_click = lambda x, y, btn: print(f"Clicked at ({x}, {y}) with button {btn}")
+frame.on_enter = lambda: print("Mouse entered")
+frame.on_exit = lambda: print("Mouse exited")
+```
+
+The `hovered` property (read-only) indicates whether the mouse is currently over an element.
+
+### Grid Cell Events
+
+Grids provide cell-level mouse events in addition to element events:
+
+| Property | Signature | Description |
+|----------|-----------|-------------|
+| `on_cell_click` | `(grid_x, grid_y, button) -> None` | Cell clicked |
+| `on_cell_enter` | `(grid_x, grid_y) -> None` | Mouse enters cell |
+| `on_cell_exit` | `(grid_x, grid_y) -> None` | Mouse leaves cell |
+| `hovered_cell` | `(x, y)` or `None` | Currently hovered cell (read-only) |
+
+See [[Grid-Interaction-Patterns]] for usage examples.
+
+### Mouse Position
+
+```python
+# Window coordinates (pixels)
+x, y = mcrfpy.getMousePos()
+```
+
+---
+
+## Event Priority
+
+### Click Dispatch Order
+
+Clicks are dispatched in reverse render order (front to back):
+
+1. **UI elements with highest z_index** receive clicks first
+2. If handled (callback returns truthy), propagation stops
+3. **Entities on grids** receive clicks next
+4. **Grid cells** receive clicks last
+
+### Keyboard Priority
+
+Keyboard events go only to the current scene's registered callback. There is no concept of "focused" UI elements for keyboard input.
+
+---
+
+## Window Events
+
+### Resize Events
+
+Window resize events are not currently exposed directly. Workaround using timer polling:
+
+```python
+last_size = mcrfpy.getWindowSize()
+
+def check_resize(dt):
+    global last_size
+    current = mcrfpy.getWindowSize()
+    if current != last_size:
+        on_resize(current)
+        last_size = current
+
+mcrfpy.setTimer("resize_check", check_resize, 100)
+```
+
+---
+
+## Testing Input
+
+Use the automation API to simulate input in tests:
+
+```python
+from mcrfpy import automation
+
+automation.keypress("W", True)   # Press W
+automation.keypress("W", False)  # Release W
+automation.click(100, 200, button=0)  # Left-click at position
+```
+
+See [[Writing-Tests]] for complete testing patterns.
