Hi Debby M , 

Thank you for reaching out about the ALT function keys within Sage 50. Did you ever find an answer for this issue?

It's quite peculiar that the ALT-A function is not working while other ALT key combinations are operational. This could be due to a recent update or an issue within the program that's affecting this specific shortcut.

The list of function keys and shortcuts provided in this article, does not mention the ALT-A function specifically, but here's what you can try to troubleshoot the issue:

1. Restart Sage 50: Sometimes a simple restart can resolve unresponsive keys.
2. Check for Updates: Ensure that Sage 50 is updated to the latest version, as this might fix any known bugs with keyboard shortcuts.
3. Custom Keyboard Settings: Check if there have been any changes in the keyboard settings within Sage 50 that might have disabled or reassigned the ALT-A function.
4. Keyboard Hardware: Test the ALT and A keys independently to ensure they are functioning correctly on your keyboard.
5. Conflict with Other Applications: Close other running applications to see if there might be a conflict where another application is intercepting the ALT-A command.
6. User Preferences: If possible, reset your Sage 50 user preferences to default as a custom setting might have overridden the ALT-A function.
7. Consult the Help Menu: Press F1 to access the online help for active windows and search for keyboard shortcuts to see if there is any new information regarding the ALT-A function.
8. Sage Knowledgebase: Check the Sage Knowledgebase for any articles on this issue or similar issues.
9. Contact Support: If none of these steps resolve the problem, it might be best to reach out directly to Sage Customer Support for further assistance.

If you require immediate functionality and as a temporary workaround, you might consider using the mouse or other navigation keys to access the invoice field. Hope this helps!

Warm Regards,

Erzsi
