Loading WWW pages to your local disk
The Options menu contain the following item:
Load to Local Disk (formerly Binary Transfer Mode)
When this toggle button is activated, clicking on hyperlinks will pop-up a Save Filedialog box:

A filename may be specified under which Mosaic will save the current document in the selected format (the valid choices are plaintext, pretty-formatted text, raw HTML, and PostScript).
P.S.: don't forget to disactivate the Load to Local Disk button to continue browsing WWW.
