Floating events

From TreoCentral

Q: How can I schedule floating events in Palm Desktop Calendar?

A: If you like to use "Floating" events in your datebook, you may have noticed that there is no GUI item allowing you to specify an event as such. In order to do get around this simply type "##f" (no quotes) in the note field of the event and upon the next syncronization, the event will show up on the Treo as a floating event.
