MacOSXHints has a slick tip on
creating clickable iCal events that are either URLs or links to files. Sure, you can add a URL to an event's
description, but with this simple method you can create an event itself that is click-able from iCal's main
day/week/month calendar view.
All you need to do for a URL is either drag it (or its icon) from a browser's address bar onto a time slot in iCal, or add a URL to an event's title and surround it with carrots like this, sans-quotes: "
This has already has become a darn handy tip for me, as I constantly add URLs to iCal events for upcoming local shows, and this takes one step out of the "so what is the site again?" process. The one thing I haven't tested yet is whether these would be click-able in iCal's pop-up reminder window. Anyone?
