# Tmux config, adapted from [1]
# For a quick refresher on some of the built-in commands, see [2]
#
# Misc tips to remember:
# * `$tmuxPrefix z` toggles a pane's "zoom" (between its current place and the full window)
# * Use `bind-key` with `-n` to create a binding that doesn't use the prefix
# * mirror an existing session with `tmux new-session -t <base session> -s <new session>`
