You have a formatting combo box located in the toolbar of boddunan editor. If you open the combobox, you can find the "preformatted" option in it.
Select the source code that you want to make preformatted and select the "preformatted" formatting from the combo box.
Alternatively, you can edit the source of your article and enclose source code within <code> and </code> tags.
When opportunity is in front of you, don't hesitate to catch it. It will never come to you again. - Maverick
