Tabs switch when umber pressed even without having ALT pressed

Hi  Simonsabin2 ,

Thank you for providing the update.
In Microsoft Fabric, when interacting with various parts of the interface such as the workspace navigator or tabs, it's possible that a UI element is receiving focus and triggering tab-switching on number key presses. After selecting an item, try clicking elsewhere on the page to see if that releases the focus from the workspace navigator. This may prevent the tab-switching behavior.
Check if there are any settings related to keyboard shortcuts or tab navigation within Microsoft Fabric’s Accessibility settings. If there’s an option to configure or disable these shortcuts, you might be able to prevent the number keys from switching tabs.
Check if there are any updates or patches for Fabric. Additionally, clear your browser cache to rule out any issues stemming from stale session data.

If your issue still persists, please consider raising a support ticket for further assistance.
