geoprocessing tool for Clip under the Editor menu

Note this is not for Clip Analysis.

I was wondering if there was a geoprocessing tool for Editor > Clip. I have a boundary shapefile which extends outside my parish border and was able to use the Clip tool under Editor to Clip off the areas that extended outside the border. Now that I have figured out this Clip tool does what I want, I would like to know if there is a geoprocessing tool which would allow me to automate this process? Any responses would be appreciated.
