+        Sets the keysym that can be used to revert the pointer to the default state.
+       
+        Pressing this key cancels any grabs, drags, selections, etc.
+       
+        The default is `Escape`. Setting this to `NoSymbol` effectively disables
+        this functionality.
+        
+        The value of the string should be the name of a keysym. The authoritative location
+        for these names is [1] with the `XKB_KEY_` prefix removed.
