It's been some time since we last checked in with Rainmaker Research's system-wide spell-checking utility Spell Catcher X, but the longstanding program is alive and well, having recently been updated to version 10.3.3. Changes include compatibility with Snow Leopard, support for 64-bit applications, expanded import capabilities, additional preference settings, a new German localization, and auto-save capabilities for reference documents. Version 10.3.3 also includes the latest Proximity Linguistic System (which ensures the program is drawing from up-to-date spelling databases), enhances DirectCorrect and program launch performance speeds, and tweaks the program code to improve handling of documents and error reports. A full list of changes is available on Rainmaker's Web site. ($39.95 new, free update, 22 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-]).
