Here’s a nice little OneNote add-on called Instant Navigator that gives you another way to find your notes. Once you install it, you can start typing any part of a note title and the results are instantly updated as you type. I rely heavily on the excellent and native OneNote search feature, but more search options are always welcome. From what I can see, the free add-on is supported on Vista with OneNote 2007.(via OneNote Extensibility)
