+# Create script only stack behavior
+The menu for assigning a behavior to a control has two additional options:
+- Create behavior from new script only stack
+- Create behavior using control script and script only stack
+Either option will prompt you for a stack name and a location for the script only stack.
+The new stack will be saved, assigned as the behavior of the control, and then added
+to the stackfiles property of control's stack.
