How are you configuring jj without interfering with using the key regularly? I used to have jj bound to ESC in VIM, loved it, but I've since trimmed back my config as I SSH into to many foreign systems to depend upon nonstandard behaviour. But I'd love to have it in Tmux.
The obvious `set -g prefix jj` throws an error that the key j is a bad key. Various experimenting with bind and unbind have not resulted in success, and I can't seem to find an example .tmux.conf with that config to copy.
