Stairways Software has released a minor maintenance and stability update to the popular macro utility Keyboard Maestro. Version 4.0.1 resolves an issue that caused slow typing speeds when simulating keystrokes, fixes a bug that enabled multiple engines to run at once, prevents simulating keys from causing hot keys to trigger, and addresses a crashing bug that affected users running Mac OS X 10.5. Also, support for Growling macro execution has been added, the Remap Forward Delete macro is now disabled by default, and a 10-second emergency timeout has been added on trigger repeat.

Two Shortcuts for App Exposé
If you want to see all the windows for a particular app via App Exposé, there are two hidden shortcuts. For either, start by pressing Command-Tab to bring up the app switcher. Then, while still holding down the Command key, press either the 1 key or the up arrow. That puts you into App Expose mode, with all of an app's windows showing, and recent documents in a row across the bottom of the screen. Let up on the Command key, and then you can press Tab to cycle through all the running apps.
