If you're doing that already and your getting stuck somewhere in the process please let me know.
On the web version on the share screen if you press ctrl + c the beat should be copied (I think it's ctrl + c on mac as well, not cmd+c). For the downloadable version there is also a copy button. Please let me know how you get on and if you still can't get it work, please let me know exactly the steps you are trying, which platform you are playing the game on (web, windows, mac, linux) and what keyboard layout you are using.
