Help Needed: Applying Keyboard Shortcut (Alt+Z) to Insert Metadata in DITA Topics

[Shivani KN]

Hello Oxygen Team,
I am trying to configure a keyboard shortcut in oXygen XML Author to automatically insert a metadata block into our DITA task and concept topics. My goal is to press Alt+Z and have a predefined metadata XML fragment inserted inside the <prolog>.
However, I am running into difficulties while creating the custom Author action.
What I Tried
I duplicated the built‑in DITA framework (so that it is editable).
I opened:
Preferences → Document Type Association → DITA (Copy) → Edit
I went to:
Author → Actions → New
The Problem
When I click New, instead of getting the “Insert Fragment” option mentioned in Oxygen documentation, I only get the “Action” dialog that contains:
ID
Name
Menu access key
Shortcut key
Activation XPath
Operation (with "Choose…")
Arguments

I do not see the “Insert XML Fragment” action type in the initial “New” dropdown.
Request for Guidance
Could you please help me understand:
How to correctly add an Insert XML Fragment action within a DITA framework?
Why the Insert Fragment / Insert XML Fragment action type is not appearing in the “New Action” dialog?
Whether DITA-specific frameworks use a different method for adding XML fragments (e.g., via custom operations, Author mode APIs, or framework extensions)?
What is the correct way to bind a keyboard shortcut (Alt+Z) to insert metadata, given the above limitations?
Any detailed steps, screenshots, or guidelines would be really appreciated, as I have followed the available instructions but still cannot access the expected Insert Fragment option.
Thank you in advance for your help!
Kind regards,
Shivani

Hi Shivani,
What you want seems similar to this blog post:
https://blog.oxygenxml.com/topics/custo ... etion.html
When the dialog to add a new action shows up, next to the Operation field you can press "Choose" and choose the "InsertFragmentOperation". Can you give us a link to the Oxygen documentation steps you were using?

Btw we also have a free Oxygen add-on which should auto generate and update the prolog when saving a topic:
