According to some links like https://www.kaggle.com/c/youtube8m/discussion/31159, the middle mouse button should paste text from the clipboard. Does it work for anyone now? That link was 4 years ago. I find Ctrl-V very inconvenient compared to middle mouse. GCS is extremely impressive on the web. But it pales compared to MobaXterm which is what I use on AWS (of course after creating a Bastion Host). I may just resort to that for the rest of the course.
