[cfry@harlequin.com (Christopher Fry)]

In a Fred window, when you insert/delete a char, 
the Save menu item under the File menu gets enabled and
a little mark gets put in the window title. [nice feature!]

I can delcare the window to not be modified with:
window-set-not-modified

Is there a way that I can explcitly declare the window to be modified?
Can I find out, programmatically, if a window is "modified" ?
