 Change some naming to be compatible with GNOME Shell 3.36.
 
-There are some naming changes in GNOME Shell, so the original project no longer works on some GNOME Shell versions (For me, it works on Fedora 31 with gnome-shell-3.34.5 and Xorg, but not on Fedora 32 with gnome-shell-3.36.3 and Xorg).

+The structure of code is:
+```js
+var KeyboardManager = class KeyBoardManager {
+    constructor() {
+        ...
+    }
+
+    _lastDeviceIsTouchscreen() {
+
+        if (!this._lastDevice)
+            return false;
+
+        let deviceType = this._lastDevice.get_device_type();
+        return deviceType == Clutter.InputDeviceType.TOUCHSCREEN_DEVICE;
+    }
+
+    ...
+}
+```
+
+This extension simply replaces `_lastDeviceIsTouchscreen` with a function that
+always returns false.
+
+In GNOME Shell 3.34 and earlier, the class was named `Keyboard` instead of
+`KeyboardManager`. So keringar's extension no longer works after GNOME Shell
+3.36.
