+Alt-tab for same class windows
+==============================
+
+
+Description
+-----------
+
+This patch is a modifications on alt-tab patch that enables alt-tabbing windows
+of the same class. Apply first [alt-tab](../alt-tab) patch to use this. Also
another feature
+is enabling reverse alt-tab when holding `Shift` key.
+
+
+Configuration Options
+---------------------
+* `tabCycleKey2` - Set this to a key that you want for class alt-tab. By
default it's set to `grave` key.

+----------------
+Thanks to Viliam Kováč for alt-tab patch which has most of the difficult part
+already taken care of.
