In edit mode, P4V supports internal and external drag-and-drop, cut and paste, and undo/redo operations in the Description fields of what is generally referred to as specs, such as job specs, workspace specs, stream specs, branch specs, and so on. In addition, you can use HTML syntax to mark up text and create hyperlinks.
In read mode, the content of Description fields renders in rich text; hyperlinks are active and, when clicked, open up in the default web browser. The following figure illustrates how the content of the Description field renders in edit versus read mode.
For submitted changelists, edit mode is only available if you have a workspace and if the changelist is yours.
The supported HTML tags in Description fields are governed by Qt's rich text engine. For details, see Qt's documentation on the supported HTML subset.
