BusyMac has bumped its “iCal Pro” software BusyCal to version 1.5.1. The update fixes a bug with time zones and improves support for scheduling meetings when syncing with the new MobileMe calendar. CalDAV syncing is also improved. New features include added preferences for meeting organizers and support for sending email invitations through additional email clients. With this release, BusyCal also becomes available in the Mac App Store. ($49.99 new in Mac App Store, $49 direct from BusyMac, free update, 6.6 MB)
Go Back and Forth Fast in Preview
If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.
The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).
