Where does LO store dummy text?

Where does LibreOffice store the dummy text that is generated in Writer when one types “dt” followed by F3? I’d like to modify the dummy text. I was able to do this in OpenOffice 3, but I don’t remember where I found it, and I’m now using LibreOffice 5.0.1.2 on Windows 7 Professional 64-bit.

Open a text document. Press Ctrl-F3 to open the Autotext dialog. In the tree view open “Standard” and find the item “Dummy Text”. Open the drow-down list from button “AutoText” and click on item “Edit”. The text opens and you can edit the text. Then save it and the altered text will be inserted on dt-F3.

The text is stored in /share/autotext/en-US/standard.bau. This is a zip-container. You can edit the text directly there after you have unzipped the container, but using the UI is more comfortable. Only if 5.0 crashes using Ctrl-F3, that is an alternative way.

Thanks. Editing through the UI worked fine. "Auto-Text was grayed out except for user-created Auto-Text entries, but I ran LO as administrator and made my edit.
