GNU Screen key bindings....

After I do CTRL-" to show all of my screen sessions, I typically use the up and down arrows to navigate up and down.

Suddenly this has changed, and instead only "j" and "k" seem to work for up and down.

This has changed in the middle of my screen session. First one changed, and then the other changed, a few days apart.

What has happened, and how can I restore my up-down cursor keys?

Usually there is a environment variable like EDITOR or PAGER which use to handle key bindings
