Thanks! I've been trying to limit excessive detail and tangents in my writing (my posts tend to be on the longer side). Great to hear I managed to strike a good balance here.

This was easily the greatest article ever written on the web clipboard interfaces.

I didn't even know about isTrusted until a couple of weeks ago when I was writing some widgets to speed up some tasks by automating a bunch of web controls. I couldn't get my auto-paste to work, discovered that flag and went down a rabbit hole of trying to over-ride a safety mechanism on my own local browser (not easy!).
