Adobe has released updates for Adobe Acrobat and Reader - 9.4 for the current 9.x versions and 8.2.5 for the older 8.x versions - to address several security vulnerabilities, along with enhancements to PDF creation, roaming profile workflows, and other bug fixes (full release notes are available in PDF form). The two patched security flaws include a crashing exploit that could allow a remote attacker to take control of your Mac. Adobe says that there "are reports that this vulnerability is being actively exploited in the wild," and thus unsurprisingly recommends that you update immediately, either from within the products or via the Adobe Product Updates page.

Edit Last Expanded Snippet in TextExpander
Sometimes you expand a snippet and realize you need to make some changes. Instead of opening TextExpander and tracking down the snippet, use the Edit Last Expanded Snippet hotkey. Once you press your hotkey combination, a window opens to let you edit and save your the last snippet you expanded.
Take the time to set your Edit Last Expanded Snippet hotkey in TextExpander's preferences, and you'll save time in the long run!
