FastScripts, the super-charged script utility for Mac OS X
FastScripts is a utility whose custom keyboard shortcuts, and superior integration with running applications make getting your work done quickly and elegantly its top priority.
Execute scripts from anywhere on your Mac, without leaving the keyboard. Anything that FastScripts can execute from its menu can be configured to run quickly in response to your desired key combination. Keyboard shortcuts defined for your application-specific scripts are only effective while that application is active, so you can define the same shortcut to do different things in different applications.
