Smile has released TextExpander 4.3 with improvements to search performance and cursor positioning accuracy. The update also fixes an issue where Return no longer worked as a delimiter, adds support for snippet creation hotkeys in applications where expansion is disabled, fixes an auto-capitalization error involving accented characters, improves abbreviation replacement in Mail’s address fields, and now allows typing to select snippets in the list. Shortly after releasing version 4.3, Smile updated TextExpander to version 4.3.1 to fix a hang when launching TextExpander with no settings.

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-]).
