Hi Vicki (ToriMac) and others with the same question,
I make extensive use of OneNote and have done so since OneNote was first introduced. Yes, everything is in OneNote.
I am using OneNote 2010 & MLO 4.3.3 pro for the following steps.
So, Yes you can link to any place in OneNote from MLO.
1. In OneNote, go to the place you want to end up from MLO. Say there is a sentence "The Properties of Granite".
2. Right click the sentence (or page, section etc).
3. Select option "Copy Link to Paragraph" or "Copy Link to Page" or "Copy Link to Section"
4. Go to MLO
5. Select line you want the link in.
6. Open the MLO Comments section of the properties area.
7. Right click the Comments area and Paste.
8. Now the Magic. Simply go to the first part of the link and insert file: -- that's all! Now the paste becomes a link!
9. Now from MLO, just click the link and OneNote goes to the specified place. OneNote will start up if it's not already going.
See if I explained the above clearly.
On going from OneNote to MLO
1. In MLO, right click and select "Copy as" / "Copy as URL"
2. In OneNote, IF you just paste - you will see the link as text. (see next step for correct way)
2. the right way. In OneNote, type something you want to click, anything.
3. Now select the word(s) you typed.
4. With the word(s) selected, press control K (edit link).
5. In the dialog box, in the address field, paste the MLO link.
6. Click OK
7. Test the new link. (a warning box comes up - click OK)
This all works fine for me and hopefully you too!
If the above works - leave a comment as I spent a half hour writing this all out
If it doesn't work - leave a comment so I can clarify the steps.
Enjoy your new enhancement to MLO and OneNote (the perfect pairing)
Thanks for asking the question!
