       - allows complete removal of dmenu, should you want to do that

+      - allows for toggleable client button bindings that have no modifiers

+ * While you can use button bindings with no modifiers without this patch in a bare dwm,

+ * toggle these on and off can be necessary in certain situations (e.g. being able to use
+ * back and forward buttons in a browser).

+ * Example bindings:
+ *     { ClkClientWin,              0,              Button8,        movemouse,      {0} },
