10.5: Edit multiple events at once in iCal

In 10.5, the iCal user interface is quite limiting. For instance, you can edit only a single event at a time. But there is something of a workaround to that problem: open multiple iCal windows at a time. Here's how. Quit iCal, then paste the following line into Terminal:

defaults write com.apple.iCal IncludeDebugMenu 1

Now launch iCal and select Debug » New Calendar Window, or just press Command-L. You can now edit an event in one window, and another event in the other window. iCal keeps the windows in sync, so that a change in one appears in the other.

[robg adds: The iCal debug menu was covered in this hint, but I thought this workaround for editing multiple events was worth sharing.]
