+# Using Input in the Editor
+
+Unlike Unity's old Input Manager, you can use the new Input System from within `EditorWindow` code as well. For example, you can gain access to pen pressure information like this:
+
+```CSharp
+class MyEditorWindow : EditorWindow
+{
+    public void OnGUI()
+    {
+        var pen = Pen.current;
+        if (pen != null)
+        {
+            var position = pen.position.ReadValue();
+            var pressure = pen.pressure.ReadValue();
+
+            //...
+        }
+    }
+}
+```
+
+This encompasses all code called from `OnGUI()` methods, which means that you can also use the Input System in property drawers, Inspectors, and other similar places.
+
+>__Note__: Unity doesn't support Actions in Edit mode.
+
+## Coordinate System
+
+The coordinate system differs between `EditorWindow` code and `UnityEngine.Screen`. `EditorWindow` code has its origin in the upper-left corner, with Y down. `UnityEngine.Screen` has it in the bottom-left corner, with Y up.
+
+The Input System compensates for that by automatically converting coordinates depending on whether you call it from your application or from Editor code. In other words, calling `Mouse.current.position.ReadValue()` from inside `EditorWindow` code returns mouse coordinates in Editor UI coordinates (Y down), and reading the position elsewhere returns it in application screen coordinates (Y up).
+
+Internally, an editor-specific Processor called `AutoWindowSpace` handles this translation.
