Here’s some attention to detail, coming in the next FastScripts 3 beta, that you won’t see in many (any?) other apps that invoke scripts with keyboard shortcuts. It detects THE SCRIPT trying to synthesize the same shortcut that invoked it. And Apple wonders why I can’t sandbox.

Screenshot of a FastScripts error dialog stating: "The script attempted to generate a keystroke ⌃⇧⌘A that would cause the script itself to be infinitely re-executed."
