To use Zed, you must first set up a site in the Site Manager (View -> Site Manager). You may leave the "username" or "password" fields empty, in this case you will be prompted upon connection.

Once connected, you may add, edit, cut, copy, rename or delete the supported objects (you can right click in the tree view or the list view).

Supported objects are determined by the ZedRoot, adding support for other objects should be easy, just refer to the existing type definitions in $ZOPEDIR/lib/python/Products/ZedRoot/types.
