- Device & OS

- Scenario
- Previewing mail merge data or editing merge fields on a laptop keyboard where function keys are mapped to media controls.
- Observed behavior
- Pressing Shift+F9 or Alt+F9 triggers system functions like adjusting volume or brightness instead of toggling the word processor's field codes.
Ensure your document is set up as a Mail Merge document and correctly connected to a valid data source before attempting to preview results or toggle field codes.
Toggle Field Codes via the Ribbon or Context Menu
Use the built-in Ribbon commands or mouse actions to toggle fields without relying on keyboard function keys.
If your keyboard's function keys are mapped to system controls, you can completely bypass them by using the graphical interface provided in the software.
Navigate to the 'Mailings' tab on the top ribbon and click the 'Preview Results' button to seamlessly switch between the raw field codes and the actual merged data.
Select the specific merge field in your document, right-click on it, and choose 'Toggle Field Codes' from the context menu to change the display for that single field.
Use the Fn Key Modifier
Bypass system media controls on modern laptop keyboards by incorporating the Fn key into your standard shortcut sequence.

Frequently Asked Questions
Why does Alt+F9 change my screen brightness instead of toggling codes?
Many modern laptops prioritize media or system controls on the F-keys by default. You need to hold the 'Fn' key simultaneously (Alt+Fn+F9) to send the standard F9 command to your word processor.
How can I lock the Fn key so F9 works normally?
You can usually enable 'Fn Lock' by pressing the Fn key + Esc simultaneously on your keyboard, or by changing the Action Keys mode in your computer's BIOS or UEFI settings.
Can I customize the toggle field shortcut?
Yes. You can customize keyboard shortcuts by going to File > Options > Customize Ribbon, clicking 'Customize' next to Keyboard shortcuts, and assigning a new, more convenient key combination to the 'ToggleFieldDisplay' command.
What happens if right-clicking a field doesn't show 'Toggle Field Codes'?
If the toggle option is missing from the context menu, ensure the text is actually inserted as a dynamic field. A real field should highlight with a gray background when clicked. If it does not, you may have just typed standard bracket characters instead of inserting a field.
