Hi, this is Gary with MacMost.com.
Let me show you how you can use the Revert To feature to go back to earlier versions
of your document.
You can use this to get back items that you've deleted from your documents or things that
you've changed.
MacMost is brought to you thanks to a great group of supporters.

So a lot of Mac users don't even know this exists.
When you're working in apps like Pages, Numbers, and Keynote every time you save you're saving
a version of that document and you can go back and look at older versions.
So say if you're writing something and you delete a paragraph and a few days later you
want to go back and recover that paragraph, you can.
Let me show you how.
Let's start from scratch here and create a blank document in Pages.
I'm going to add some text to it.
Now that I've done all this work it's probably a good idea for me to save the document.
I can use File, Save or Command S to save it.
Since this is the first time I'm saving it.
Now I'm going to type another line.
Now that I've done some work I want to save it again so I'm going to use Command S again.
Now I'm going to type a third line.
Now my document is getting really long I want to make sure I'm saving it every once in a
while.
So Command S again.
Then a fourth line.
Now I have four lines in the document.
It seems like I have the normal document here where I simply save the document and if I
open it again I would get back to these four lines of text.
But there's actually a lot more going on because every time I saved, I saved a version of the
document and I can revert to any of those versions.
If I go to File I can see Revert To.
There's a few things there.
I've got Last Saved.
Now since I haven't saved yet after typing the fourth line I can jump right back to the
last saved version.
I could also go to Browse All Versions.
Let's go to that.
You're going to go into an interface that looks a lot like Time Machine.
On the left you have the current document.
On the right you have this stack of old versions.
You can see the most recent saved version only has three lines.
I can use these arrows here to go back to previous versions.
There's one with two lines.
There's with one line and there's the original version there.
I can choose any one of these and use the Restore button.
What will happen is I will restore to this version of the document.
So I'll hit Restore and now I'm back to a version of the document that doesn't have
the fourth line.
Now even if you know how to use this there's a lot more functionality here.
For instance what happened to that fourth line?
Well, it turns out I could go to Revert To, Browse All Versions and it actually saved
that version.
So if you want to revert back to before you did the Revert To you can.
Which makes it a nice safe operation to do.
In case you make a mistake you can actually go back to this one.
Another thing you can do is you can Copy and Paste between these.
I can click here on this document.
You can see it enlarges it but I'm still in this mode here where I've got Done and Restore
and I have the other versions back here.
But I can actually work in the document.
So I can add new stuff.
See there's a cursor so I can select things.
I can also here and enlarge this.
Now you may use this to get a better view of the version of the document.
But you can also select something, copy it with Command C, go over here to this version
and Paste it in.
That's right!
You can work on the document while you're in this mode.
Another thing you could do is you can hold the Option key and notice the Restore button
here changes to Restore Copy.
You can keep this current version, but save this version out as a copy of the document.
A few other things going on.
One is you've got this Timeline here on the right which since I just started working on
this document there's not much there.
But if I've been revising this document for months I could easily jump back to an earlier
version.
So maybe if I did something on my first draft and I want to bring it back I can easily jump
two to three months back and find it.
Another thing to note is that the file sizes are going to remain under control because
it's not saving a completely new file each time.
It's saving changes.
So you have your current document with everything there but it remembers what changes there
were between that and the last revision and the revision before that.
So instead of having ten different copies of the same file it's actually going to have
one copy of the file and then the changes going back in time.
So actually the file size is staying quite small.
Now if you save a document like this and you Close it and then you go to Open it again,
so I'll open Recent, I've got it here and if I start working on the document, I'll just
hit return here, I'll notice that now I have Last Opened.
In fact if I start working here and I hit Save and then I start working again, now when
I go here I have three options.
I have the last saved version, I have the last opened versions, so I can revert all
the way back to the point where I opened it even if I saved a dozen times I can jump back
to when I opened the file this morning and I can go to Browse All Versions to see everything.
This works in more places than just Pages.
For instance in Keynote you've got Revert To there as well and it works exactly the
same way.
Also in Numbers you've got it there as well.
It's not just those three apps.
For instance you can use it in TextEdit.
So TextEdit also has those.
Technically this is available for lots of other apps to use.
One example of a third party app that has implemented it is Pixelmator.
So here I have a document with just some squiggles in it and I can go to Revert To and there's
Last Saved, Last Opened, Browse All Versions.
So you can see how handy a feature this is but here's what I recommend.
Don't wait until the first time you really need this to use it.
Practice right now.
So open up a document in Pages or maybe if you use Numbers more use that and just create
a sample document, save it a bunch of times, close the document and then open the document.
Use the Revert To feature and see how it works so the first time you really need it you already
have got some experience using it.
