The Tridion Development Pane is the main “viewing” window of the Tridion interface. This section is not intended to teach you how to build or edit sites just yet, but rather provide an overview of how Tridion looks in your browser.
Instructions
Once you select a publication/website from the publication list, the contents of that publication will appear in the center area, or the development pane.
Note that only folders will appear in the publication list. Individual items, like pages and components, will only display in the development pane.
You will see a yellow Building Blocks folder and a pink Root folder. These are the only two folders you will work in. The Categories and Keywords folder is not used by the majority of YSM websites, and can be ignored. (Figure 3)
Anytime you open a page or component in the development pane, that page or component will open in a new tab or window of your browser.
