Search for "Parameter", drag it in, rename it to
"enableBackwardTypeInference" and set the value to "true".
Unfortunately, Kepler does not have the model-specfic context menu that
allows one to add a parameter by right clicking on the background,
There is probably a bug here to be reported, which I will do now.

Dear Kepler users,
I have downloaded and ran suite 'kepler' from the repository (I end
upt with kepler version 'trunk'). I can't find out how to set the
enableBackwardTypeInference parameter for a given actor. I just can't
find this parameter!
I right-click on the actor canvas but none of the offered menu-options
seems to have the enableBackwardTypeInference (see attached image or
link to http://tinypic.com/r/2ypknwn/5 to see the options-menu I get)
Sounds like a stupid question, but I am baffled here.
