What's "Enhanced User Interface?"

 

The GET TURN-BY-TURN DIRECTIONS section of the description of the Nuvi 1450 contains this sentence:

"With the 1450's enhanced user interface, you can slide your finger to conveniently scroll between screens."

Anyone know what this means? The owner's manual, of course, doesn't mention it.

--
"No misfortune is so bad that whining about it won't make it worse."

what happens...

if you "slide your finger" top to bottom?

Does it scrolldown on a multi-page screen?
