If you're like me you probably have a few OneNote pages or sections that you use frequently. For example, a to do list, daily log, team notebook homepage, or project status page.
I like to have instant access to those things with a simple keyboard shortcut, whether OneNote is currently open or not. It really improves my workflow. I do that by creating windows shortcuts directly to those pages as follows:
Voila. You now have a direct keyboard shortcut to that page or section in OneNote. Close OneNote and try it out. Just press the keyboard combination and OneNote should open up to that page, no matter what app you're in. It's even useful while you're actually in OneNote but on another page.
If you're using Vista, there's a nice bonus feature here. You can hit the Windows key on your keyboard. This will pop the start menu and you'll have your cursor in the search box. Type the first few letters in the name of your shortcut. For example: "ToDo". Vista should instantly search (assuming it's already indexed) and your shortcut should pop right to the top. When it's selected, hit enter and it will immediately launch OneNote straight to that page. I find this handy if I have a lot of page shortcuts and it's hard to remember keyboard combinations for all of them. I can just hit the windows key, type a couple of characters, then hit enter.
You could even have a naming convention for your OneNote shortcuts, such as "ONZ1 ToDo List" and "ONZ2 Project Status" etc. If they all started with ONZ, then you could just hit the Windows key and type in "ONZ" and then Vista search would instantly show all the shortcuts with that in it. You could see the list and then just hit the number to narrow to the particular shortcut, or just arrow key through them and pick one.
Of course, if you don't have Vista but have some other desktop search tool that could work too.
