Using Side Notes
I take a lot of notes. All day, every day, I'm taking, searching, updating, referring to notes that I've taken. I used to do that on paper, and ended up with scraps of paper scattered all over my desk. Not only hard to search, impossible to find (and hard to share).
Now I use Microsoft OneNote's Side Note feature for that purpose.
If I get an idea I just press Windows Key + N and up comes a Side Note, just ready and waiting for me to add some text.
I can type my notes, create a list, insert something useful I found on a website, tag the notes with To-Do items that integrate with Outlook, sketch a little diagram...even record audio if I want to. And OneNote captures it for me all right there.
When I close the side note OneNote will save it for me in the Unfiled Notes section. Or, I can click the Pages group on the Ribbon, choose "Move Page" and select what section I'd like that quick note saved to.
You're not limited to one side note at a time either. I often have 3 or 4 different side note windows open and running as I brain storm issues, refer to other notes and add or edit content.
