I work with Adobe Photoshop CS6 and have a script that allows one to export your Action Script files into an editable XML file. You can make the necessary changes within the XML file without having to delete and re-record your commands in Photoshop. Once completed save the XML file and have Photoshop run the included script to change the XML back into an ATN file.

Action File To XML

XML To Action File

Just run both of the Adobe JavaScript JSX files and they will install into Photoshop.
