An online system provides users with tools to annotate publications and share such annotations with other users. Publications annotated by a community of users become a richer source of information for the community.

In an electronic file system, preview information is provided to the user during a drag operation of a selected object onto a target object. The information indicates what type(s) of action is to be taken should the selected object be dropped onto the target object. The action(s) to be taken may depend upon the type of the selected object and / or the type of the target object. For example, where the selected object is an item and the target object is a persisted auto-list, the action may include adding, removing, or modifying one or more properties of the selected object to conform to one or more criteria defined by the persisted auto-list. Also, numerical feedback may be provided to the user where multiple objects are selected. For example, where seven objects are selected, the textual number “7” may appear next to the cursor.
