It's like a News Ticker that you see along the bottom of news channels.
It will open another small window and will then scroll through all the latest posts, articles, blogs, property listings, jobs, etc that are current, however with a bonus, in that you can click on any particular subject and it will take you directly there.
Then, if you navigate away from EOS (why you should want to I don't know, as you should subjugate the rest of eternity to supporting EOS and never, ever, ever navigate away from us, ever!) then the 'ticker' stays on your desktop, and when you see something of interest, click on it.
Try it!
