Update some iCal event info without editing

If you double-click an event in the 10.5 version of iCal, you get a little pop-up window with some details and Edit and Done buttons, as you probably already know. This window might look worthless for editing, but even if you don’t press the Edit button, if you drag and drop some text onto this pop-up window, the text will be added to the notes field of the displayed event.

I did this by accident and was surprised it happened, so I tried a few more things. Drag and drop a file, and it is added as an attachment. Drag and drop a person from Address Book, and they are added as an attendee. You can also drag multiple people, or an existing group, to have them all added as attendees. Drag a URL, and its added as a clickable URL. So despite appearances, you can actually do some basic editing in the event info pop-up window.
