Yes, that is what I meant and thank you. I will formally recommend this be
added to Microsoft.
If you have MS Office 2003, you could try using "Microsoft Office
Document Image Writer". It creates .MDI files which can be
text-searched. However, unlike Snapshot, AFAIK there is no free viewer
available.
Alternatively, you could print to PDF, which is programmatically rather
difficult without Acrobat/Distiller.
