No need to even copy/paste anything. As a Steam game hub moderator, I can tell you one of the most used tools in my arsenal of moderator tools is the Google Translate extension for Chrome. I can highlight what you said and it pops up a small window with it automatically translated.
I can't wait for the day that anyone can type any language and the browser just automatically translates it and we can all chat without language ever being an issue.
Make sure to go check it out!
Edit: I got the sketchfab stuff working, its pretty neat.
