Changing Schematic Property Value in CIW Window

I had a way to change a schematic property value in the CIW window but I can't remember it.

Example:

A transistor device has the parameters of length and width.  These devices are set up with a range of allowed values.  I want to be able to use a value that is not in the range.  I have been able to achieve this by setting the value in the CIW.
