UnsavedVariables
is an option for Manipulate, DynamicModule, and related functions that specifies local symbols that should not be saved when the notebook containing them is saved.
Details

- The typical usage is UnsavedVariables:>{var1, var2,…}.
- The DynamicModule containing the local variable var will save neither the ownvalue nor any other value associated with var.
