Hi I successfully followed the tutorial on how to create a new file type over here: https://netbeans.apache.org/tutorials/nbm-filetype.html
I created the stub Action listener/handler. The action I would like to code up is to run/view the new file in a browser, just like you can do with an html file with its "Run File Shift+F6" right-click menu item. I was looking for the code that implements that action, or some other clue as to how to go about it. Thanks for any pointers! Peter
