What is this? Well, simple. If there is a value you need to copy frequently to your clipboard, but you're lazy like me, create a bookmark with the value equal to source. Replace <value you would like to copy here> with the value you'd like to copy. Only works on Chrome.

1. Go to chrome://flags/#enable-experimental-web-platform-features and enable Experimental Web Platform features, without it this doesn't work. 🤷
2. Replace <value you would like to copy here> in source.js to the value of your choosing.
3. Copy the entire script into the URL field of your bookmark.

I frequently LFG in Destiny 2, but with the move to Steam the /join command requires a Steam64 ID. I found myself using Steam id finder too often to find my Steam 64 ID.
