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 this be what you are looking for?

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.)

Not sure what "Layers" can be in PDF.
