The Select Document dialog is used in various situations where a document needs to be selected, such as when opening a document, or by certain properties which point to documents within the course, such as the Navigation Button <Navigate To> property.
The tree shows all documents in the project, along with a tagged tree aggregating the available documents by tags for quick access. In some usage scenarios, only documents of specific types will be available in the tree, as appropriate.
On the right-hand side of the dialog, a snapshot preview of the selected document is shown, unless the Show Snapshot checkbox is unchecked. The Preview link can be used to open a live preview of the selected document.
