Hi @Guille Martín
Does this issue occur with other Office desktop apps, such as Word?
- Please check the keyboard layout. As the following image says, Keys for other layouts might not correspond exactly to the keys on a US keyboard.
- You may also check the input language keyboard when editing notbooks. Please swithch to English (US keyboard) to check this issue.
- Then I suggest you update OneNote to the newest version via clicking File > Account > Update Options > Update Now.
Any updates, welcome to post back.
