OCR stands for optical character recognition. Basically, whenever
there is a picture, OCR can be used to recognize text that is on the
picture. Some PDF files are actually images that have text in them.
OCR can be used to analyze the picture and pick the text out of the
picture, then the screen reader can read the text.
I hope this was a good enough explanation.

What is the "o c r engine?" Thanks. Felix says he can read pdf
files but can't interact with pdf files, for example, to see how a
particular word is spelled.

many pdfs are not pictures of words or screen readers would not be
able to
read them. There is no o c r engine in adobe reader or preview.

No, pictures of words. Some of what people read online at some
sites is
pictures of words, rather than text. It all looks like text to
sighted
people. But to the screen reader, it is pictures.
Felix says that's what PDF files are. Pictures of words.

Can't say with pictures as I am sure as far as I can tell it won't
interact with those, but then what would there to be interacting
with.
However, with links that were textual in nature, can be interacted
with where previously that was not possible.

there is nothing for the screen reader to get it's hooks into to
read. Felix's words.
So does Safari's latest upgrade now convert those pictures into
text
in the links? Just wondering how its done to make it work.
Or does it just read most stuff but not all.

Folks, maybe I just hadn't tried this in a while, but do you
recall a
time when you couldn't interact with a link? Well the most recent
version of Safari available to you will allow you to interact with
links on a page. I mean interact with them so that you can
navigate
character by character which was not possible previously. Now, is
this
cool or what. I just suddenly started doing it and it just
occurred
to
me that I was actually doing it.
