There is no command in Mathematica called Snapshot and that is why it did not work.

Yup. I'd be fine with that. I just want a general function that will generate the corresponding snapshot DynamicModule with initial parameters for a given arbitrary Manipulate.

The InputForm is a neat idea! I'm not able to do it to a variable however, only if I type it after the output box itself. Also, it, as you point out, keeps it in Manipulate form, with variables as controls following the expression.

I'd like to do something like this:then do e.g.to get
Is perhaps the easiest way to do and then fiddle with the First for the expression and the Rest for the controls from which I'd extract the starting values?

I thought there might be a built-in function that does the equivalent of the Snapshot Button in the Manipulate.
