 Hi, this is Dr. Dunn. A couple of questions have come up from students asking how they can be sure that they're saving their work when they're in Posit Cloud. And it hadn't occurred to me until recently that some of you may never have worked with a computer that actually used what we used to call floppy disk. And in Posit Cloud, like many programs, they use the old floppy disk as an icon to tell you where the save button is. If you look here in the Quick Start, I just opened up the Quick Start worksheet. And if I look up here at the very top, you can see there's two little squares there. And those are floppy disks. And when I hover over it, it says save all open documents. And so you can just click that, and that'll save all the documents you have open if you've got more than one. If you look down here in the Quick Start itself, if you look closely, you can see a grayed out image of another floppy disk icon there. And the reason it's grayed out is that we've not made any changes yet. If you look up here next to the save all, there's another one of these grayed out individuals save the current document that you're working on, icons. If I put my cursor here, say I'm going to start typing in my name, and as soon as I type, I've changed that document. You can see the name now has an asterisk by it to tell you that it's been changed, but not saved. That's what that tells you. So you can click either this floppy disk icon to save it or click that one and save your changes. So do that often. That'll save a little bit of heartbreak. And I hope this helps.
