Secure access to EC2 using Session Manager and Port forwarding (opens in new tab)

Does anyone know how to make it so CLI shortcuts like Ctrl+Y ("yanking" in Bash or IPython) don't completely break AWS Session Manager? This is the main thing keeping me from switching to AWS SSM.

Accessing EC2 instance using SSH keys involves some risk around it. AWS has made getting access secure and intuitive with the use Session Manager.
