tried some more, and figured out how to get part of it working. But
then it stops. Apparently Apple's dictionary feature explicitly checks
whether the object is a textview or a webview, and refuses to finish
if it's not. If you think strongly about this you can join me in
pressing Apple to make this feature more widely available (i.e. any
accessible text area).

I've tried implementing the missing parametrized attributes and also
change the role to AXTextArea, but it still did not work. It may be
that the deamon has NSTextView and WebView hard coded, or perhaps it
requires some private method. Anyway, I'm giving up.

I didn't know that goes through accessibility. That's strange, as
you can turn that off. Anyway, nothing is documented and I have no
idea what it calls to figure things out. It does not seem to request
any attribute. I guess parametrized attributes like
AXRangeForPosition and AXAttributedStringForRange can be relevant,
and PDFDisplayView does not implement those. But those are quite
hard to implement as PDFKit does not make it easy to find the text
at a point, and moreover as PDFDisplayview is private we don't know
exactly what's implemented and what will be implemented in the future.

calls to
SKPDFView when you hit control-cmd-d, but it doesn't end up getting
any text

I messed with it for a few minutes, but it would take me quite a
while to
understand the accessibility code.
