SPMUG 649 Add Login Items from the Dock
In Mac OS X, a "login" item is
equivalent to a "startup item" in Mac OS 9 -- an item that auto-launches
when you log into your user account. You can add items in the "Account"
preference pane, but you can also add them directly from the Dock. If an
item is in the Dock, possibly because it's currently running, just
click-and-hold on its icon and choose "Open at Login" from the
contextual menu that appears. Design Tools Monthly
