Search for tagged notes
If you previously added tags to any of your notes, Microsoft Office OneNote 2007 can search your notes by tag keywords and present the results in an easy-to-read summary.
On the Standard toolbar, click the arrow next to the Tags button, and then click Show all Tagged Notes.
In the Tags Summary pane, narrow the Search scope if needed, and then click Refresh Results.
Note You can use the To Do note tag as a check box to indicate whether you have followed up on an action item. In the Tags Summary task pane, click to check off any To Do tags to indicate their completion.
