I’m afraid this is not possible. In order for this to happen, a OneNote page would have to be come much more complicated, there is no way to ‘fine-tune’ spell-checking that specifically.
However, you can tinker with the spell checking options in
Try experimenting with some of the highlighted options above. For example, you can have it suggest words from the main dictionary only, or use a custom dictionary, or even edit the word list yourself…
You can also disable spell checking or only have it check it in one sweep. To have it check in one sweep, uncheck
Check spelling as you type.
A variation on the language support trick from Petri above seems to do what you want:
- Select a block of text in your document that you want to disable for spell checking
- Go to the Review tab and select Language > Set Proofing Language
- Select a language for which you and your likely readers have no dictionary, e.g. Afrikaans, Cherokee etc. work for me.
The other text will still default to being in the original language, e.g. English (UK) in my case and will still be spell checked as normal.
You can also keep the proofing language pane open to make it quicker to apply the same change to multiple areas of your document.
I guess the reason for this functionality is for when you quote something in another language, you can spell check it correctly.
Install OneTastic addin, which has one of macros, named “No spell check”
P.S. Onetastic is an add-in, which is made by Microsoft OneNote team developer, and has lots of useful features. You can trust it.
The trick works for me is to set page language to something you don’t have language support in your computer. For example I changed page language to “Afrikaans”. Then OneNote does not make spelling checking for this page because Afrikaans -dictionary is missing.
I discovered by accident that if you precede the paragraph where you don’t want red spell checking marks to show up with the symbol for, “therefore” then that paragraph will not show words that contain spelling errors underlined.
You can make the symbol for, “therefore” (3dots) by holding down the Alt key then typing 8756 then releasing the Alt key. This works on Windows anyway. I don’t know if it works on other operating systems.
If you don’t want the symbol to show up you can just select the symbol and make it white or the same color as the background if you are using a colored background. You could also reduce it’s font size to 1.
Note: this will only get rid of the red spell check marks; it will not turn spell check as you type off. So words that are normally corrected as you type such as: recieve will still be corrected to: receive as you type.
