Lisa, Yes, the Braille Lite M20 and M40 both have the ability to scroll automatically with the use of the ER chord. But please, please, *please* look into your options before making the decision to go with a Braille Lite Millennium! The Braille Note and Braille Note PK offer more functionality than the Braille Lite M20, at a comparable price. The Braille Note is slightly larger but offers a fairly stable OS, Internet connectivity, MP3 playback, Bookshare decryption, an Outlook-style planner that can be synchroniced with Outlook, and a host of other useful features. The Braille Note PK is smaller and lighter than the M20 but just as full-featured; offers Internet connectivity and wireless capability; and has some other enhancements over the original Braille Note. I can't speak for this machine's stability, so you might want to do further research and find someone who can. Freedom Scientific itself offers the PAC-Mate line, which is bulkier but more robust in terms of features than the M20. Check with FS at 800-444-4443 to determine if PAC-Mates can scroll: I think they can. Both the FS PacMate and the Braille Note support compact flash cards more seamlessly than the Braille Lite, offer more full-featured software, and can be upgraded to include GPS functionality. Unless you are investing in the Braille Lite because of its sheer simplicity at the expense of extra features, I would encourage you to spend roughly the same amount of money on a product that does more. Best, Chancey
