[Info-vax] off-topic: imstamtameous paging of a PDF file on an iPad

[Phillip Helbig undress to reply]

I sometimes use LaTeX to create a PDF file which I can view in 
full-screen mode and step through it page by page but with no scrolling, 
imitated page turning, sliding, and so on.  The main reason I want to 
page through instantaneously is so that I can build up a slide with 
bullet points line by line.  Every PDF viewer I've seen can do this, 
except those for the iPad.  I downloaded 6--8 from the App Store and 
none of them seem able to do what I want.

The closest I've come is with the native Books app, which has the full
page and individual pages as icons at the bottom.  Thankfully, I have
VERY thin fingers, so can get what I want by tapping them one by one.  
But that is error-prone, especially when giving a presentation.  What I 
want is similar functionality just by tapping.

Any ideas?

(Of course, I don't actually write several pages, each with one bullet
point more than the previous one.  I write a normal LaTeX file with just
the complete pages.  I then have a script which reads it and creates
LaTeX files for the individual pages.  Via nested \input commands in a
new LaTeX file to the desired structure is created, optionally including
a footer or whatever.  (Thus, even in the script-generated files, there
is no text duplicated.)  After the last page, the completed pages are
\input one by one so that I can easily "go back" to a given slide. 
While I've often seen the line-by-line structure, which presumably many
packages implement in a similar manner, I'm surprised to see a speaker
stepping back through previous slides line by line.  I started this 25 
years ago.  There might be presentation packages which do something 
similar, but I am content to concentrate on the logical structure and 
have it come out looking like I want it for a presentation.)
