In making a presentation from a PDF file using a Mac or PC, you can almost always move forward and backward through the slides (aka document pages) using the left and right Arrow keys.
But is there a way to step forward and back through _Layers_ on a single slide using Arrow keys, or any other designated keys?
That is, suppose there's a situation where you want to start with a master slide having a background graphic and then add 4 or 5 additional graphic elements to it in sequence.
Doing this by creating a single slide/page having a sequence of 4 or 5 separate Layers can be more convenient that using the same number of successive slides. [Reduced file space, and only have to edit the one master slide if you change the background.]
You can then step through this sequence in a presentation by creating mouse-clickable Links (Buttons) on the master slide. But when you're at a podium, clicking keyboard keys can be a lot easier than using a mouse -- especially on a darkened stage or when using an unfamiliar computer.
I haven't found any way to create keystroke-activated Links in PDF documents -- at least, not using Adobe Acrobat or Adobe Reader. Do such exist?

PDF's main purpose is not presentations.
PowerPoint can do this [1]
Keynote, probably, but I haven't tried it.

Might be -- it's titled "Keys for navigating a PDF".
At first glance, however, neither of the formal Adobe PDF terms "Layer" or "Links" seems to appear anywhere in it.
The opening table does show, however, in addition to key commands for First, Last, Previous, and Next _Page_, two other key commands for Next and Previous _Screen_.
Maybe that's what I'm after -- will have to try it. (The fat "Adobe PDF Bible" that's on my bookshelf doesn't seem to have any index entries for "Screen" used in this sense, however.)

And this OP goes to the 505 page users' guide on his HD -- the one that Adobe supplied at the time he purchased his copy of Adobe Acrobat Standard 7.0, and that can also be downloaded from Adobe's web site -- and copies and pastes the following:
About Adobe PDF layers (boldface title line)
Acrobat supports the display, navigation, and printing of layered Adobe PDF content output by applications such as Adobe InDesign, AutoCAD, and Visio.
You can rename and merge layers, change the properties of layers, and add actions to layers. You can also lock layers to prevent them from being hidden.
To create layers while exporting InDesign CS or later documents to PDF, make sure that Compatibility is set to Acrobat 6 (PDF 1.5) and that Create Acrobat Layers is selected in the Export PDF dialog box.
and shortly thereafter
Viewing layers (another boldface title line)
Information can be stored on different layers of an Adobe PDF document. The layers that appear in the PDF document are based on the layers created in the original application. You can examine the layers and show or hide the content associated with each layer by using the Layers tab in the Navigation pane. For more information on working with layers, see About Adobe PDF layers.
Don't have Warnock's ear; do at least attempt to know what I'm talking about before posting; and do definitely know how to use "Kill" files.
