ExtendScript Toolkit for Adobe CS5 applications
The ExtendScript Toolkit (ESTK) 3.5 is a development and debugging tool for JavaScript scripts included with Adobe Creative Suite 5 and applications such as Bridge, Photoshop, Illustrator, InDesign, and After Effects. The ESTK has many features that make it easier to use than a text editor, including a built-in syntax checker that identifies where the problems are in your script and tries to explain how to fix them, and the ability to run your scripts right from the ESTK without saving the file.
 
The ESTK also includes a JavaScript debugger that allows you to:
    ● Single-step through JavaScript scripts (JS or JSX files) inside an application
    ● Inspect all data for a running script
    ● Set and execute breakpoints
 
ESTK 3.5 contains a number of improvements related to its usability and stability, including:
    ● Automatic document backup
    ● Option to open new documents in a floating window
    ● Option to display the Object Model Viewer in a dockable window
    ● Fast access to clear the Console pane
    ● Improved output of debugging sessions
