+"""
+This plugin exports four functions - up, down, left and right - that when called will
+move window focus to the first window in that general direction. Focussing is based
+entirely on position and geometry, so is independent of screens, layouts and whether
+windows are floating or tiled. It can also move focus to and from empty screens.
+
+Example usage:
+
+    import traverse
+
+    keys.extend([
+        Key([mod], 'k', lazy.function(traverse.up)),
+        Key([mod], 'j', lazy.function(traverse.down)),
