If you ever want a listing of all of the ‘on’ and ‘function’ handlers available in a suite, here’s a little script that will do it for you. I’ve also included a couple of utility functions at the end (they’re not used by the main script) to let you check whether a particular script exists in a suite, or whether a particular handler is found in a script.
Just download this script (it’s called ListAllHandlers.script) and drag it into the Scripts tab of a new (or old) suite. When you run it, select a suite and it will give a complete listing of the handlers in that suite. As always, feel free to adapt this for your own needs.
