John, the additional tools are nice, but I've found the most success in
adding the additional step of first "printing" to Microsoft Office Document
Image Writer (MDI), which has a print driver similar to "Send to OneNote".
The benefit here, is that MDI will automatically orient pages when you run
its OCR, and it also lets you choose orientation for one page at a time. If
you bring the document into OneNote the right way, pages come in with the
desired orientation. The benefit here is that when pages are imported with
this extra step, they are recognized by the OneNote OCR. Pages that come in
the wrong orientation and later manipulated by the powertoys, don't get
recognized by the OCR and can't be searched later.
To do this, first manipulate the document in MDI (as described above) and
save the document as a *.MDI file on your hard drive. Then open a blank
OneNote page and copy the file from Windows Explorer to the blank page. The
page orientations come in the right way, but it doesn't seem to work if you
"Send to OneNote" from MDI; you have to copy the *.mdi file from Windows
explorer.
