Frequently Asked Questions
Why did the expand and collapse controls disappear in OneNote?
This was a known bug caused by a Microsoft 365 update that integrated the new Copilot features. The addition of the Copilot icon in the margin inadvertently interfered with or replaced the traditional expand and collapse indicators for hierarchical lists.
Is my hidden text lost if the expand icon is missing?
No, your text and data are completely safe. The issue only affects the user interface button. Your sub-items are still there and can be revealed using keyboard shortcuts, such as Alt + Shift + Equals (=).
Can I disable Copilot in OneNote to restore the old interface?
Standard users typically cannot disable the Copilot integration directly from the OneNote interface to revert the margin changes. The recommended solution is to apply the latest Microsoft 365 updates, which contain the official patch for this interface bug.
How can I expand all levels of my outline at once?
To expand every level of a hierarchical list simultaneously, place your cursor within the list and press "Alt + Shift + 0" (zero) on your keyboard.
