- [Instructor] In an earlier chapter,
I talked about making navigation buttons.
You know, buttons that you can click
to jump to go from one page to another.
Now while these buttons sometimes don't work
in tablet or mobile PDF readers,
they still are a really important way
to let your audience move
from one page to another.
But there's a secret side to buttons.
Each button that you include in the PDF
adds a little bit of file size.
Even if you put your buttons on a master page,
InDesign creates a new button for every page of your PDF.
So if you're trying to keep your file size down
to really small, that can be a problem.
So, here's a quick trick that I learned from
Acrobat guru, Ted Padova, that I often use
on longer documents with a lot of buttons.
Like in InDesign Magazine.
Instead of putting my buttons on a master page,
or on every page of the document,
I only put them on the first page.
For example, here inside the interactive brochure file
from the exercise files folder,
you'll see that I have several buttons
down here at the bottom of the screen.
And I've taken them off the master page
and pasted them in the same location
on just the first page.
They don't appear on the second or any other pages.
For example, I'll press shift page down,
and you can see they're not there on this page.
Now instead of taking the time right now
to export this PDF,
I've already created it, and I'll just switch over
to looking at it in Acrobat.
Now these buttons down here do work.
For example, I'll click the next page button
and you'll see it jumps me to page two.
But there are no buttons here to go any further.
So, okay, now I'll go back to page one,
by clicking on the previous page button up here.
Now, here's the trick.
I need to select those buttons and duplicate them
on all of the other pages.
To do that, I need Acrobat's special tools,
so I'm going to open the tools panel over here,
and I'm going to search for a tool called select.
And as you know, this Acrobat interface is different
in different versions of the program.
But just search around for the rich media select tool.
This lets me select
any of the interactive objects on my page.
All I need to do is just drag over this area down here,
and that selects all of those buttons.
Now, I'm going to right click,
or control click with a one-button mouse,
to show the context menu.
And inside this context menu I'm going to choose
duplicate across pages.
Then, from this dialog box I'm going to choose all,
that way I'll get the buttons on every page.
I'll just click okay and it takes about one second
and then it's done.
Let's go check it out.
I'll switch back to the hand tool here,
so we can see this in action.
Here we are on page one,
and I'll click the next page button down here,
and now you can see the buttons show up
on all of my pages.
And the good news is, because we duplicated these
in Acrobat it added almost nothing to the file size.
Now, if your document isn't too long,
or you don't have too many buttons,
it's probably not worth taking this extra step.
I would just do the buttons in InDesign.
But if you do have a long document,
you should definitely try this out.
See if it helps keep your file size down.
