# This section is entirely for 'nested' tmux -- I don't use it much anymore

# and then want to ssh into some long-running server (where you *also* want to have persistent sessions)
# To make this work, you only need to copy your .tmux.conf (this file) onto that server
# then you can move back and forth between controlling which level of nesting you're controlling with
# shift+up and shift+down.
