The input value "use" is not recognized as a valid input inside hammer but it will function ingame using the targetname of the env_funnel entity and providing "use" as the target input value, you don't need to fill in the parameter override field.
 
Another way of activating this entity is ingame by using the following command in the developers console: "ent_fire <tagetname_funnel> use"
This entity has no other function than showing these particles/sprites. A similar effect can be created by creating a new particle effect yourself.
