A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Unfortunately this feature is missing from OneNote 2013. I will pass this request to the team and see if we can bring it back.
Please do push this feature request to the OneNote development team. While pushing out Windows 8 and Office 2013 in our department (major University), we immediately got complaints from users that reply on this feature. These users track hundreds of related documents (relating to Grants, Research, Admissions, etc) in a wide variety of locations on shared drives. Without OneNote this would be much harder to do and extremely inefficient.
In Office 2010 you could navigate with Windows Explorer to your file or folder, right-click on the path in the address, chose “Copy Address,” Alt+tab to OneNote and Ctrl-V to paste the link. In Windows 8, "Copy Address” is still on the context menu in the address field of Windows Explorer, but it won’t paste anything with Ctrl+V, and with the mouse (wasting precious time and wrist comfort) it will only paste if you choose the option paste as text. Or you can do Alt+H, V, T and then it will paste as text (Alt+H, V, M, and Alt+H, V, K give no results). Or you can do it through the Insert, Link, Browse to file, copy address, close, tab to Address in the Link Dialog window and paste. It works, but is more cumbersome.
Also, it is worth noting that OneNote integration is the only reason we use Outlook as a mail client. An argument could be made that is now the major reason we use Office applications in general. Please bring this feature back.
