it's me answering my own question here. after playing around some, i realized that when hitting Control-N while in OneNote, the Send To OneNote is greyed out / is inactive. That's because OneNote doesn't send to itself in that feature. However, if one is in Word, Excel, etc. that hitting Control-N results in that middle icon not being greyed out & so one has the ability to send the viewed page to OneNote. I'm still unclear though about Sending to OneNote (using Control-N) while on an Internet page which still shows the greyed out Control-D icon. I think that may be a resources issue with my computer, which at the present time does not have Explorer working. This is an ongoing search for a solution.
