Thanks for the feedback. Me too, I’m happy with the script 
For a maximum of convenience you can map the trigger to the Media Eject key of your keyboard (⏏) as shown in one of the posts above. (I have not included that trigger in the downloadable macro because that key is probably device-specific.)
But: If you are going to map it to the ⏏ key, then I recommend to not do it as I have shown it in the post above: Instead of selecting “ignoring modifiers” I recommend to select “with these modifiers” with no modifier key selected. Like this:
The reason is, with that trigger you are still able to use the other, system functions of the ⏏ key. (The system functions of the ⏏ key are described here.)
