# When a smaller terminal connects to a tmux client, it shrinks to fit it. The
# clients attached with bigger displays see this constrained view.
# aggressive-resize makes it such that the window is only resized if the smaller
# client is actively looking at it.

# In a shell environment in a terminal in tmux, the env var $TMUX will be
# defined to something like "/tmp/tmux-23273/default,31101,0". Outside tmux,
# $TMUX will be undefined.

# Notation to address a specific pane
# SESSION_NAME:WINDOW_INDEX.PANE_NUMBER (Example: foo:2.1 i.e. Pane 1 in Window 2 of Session foo)

# To print a message containing tmux variable values to stdout use '-p' option in display-message
#   tmux display-message -p '#{session_name}:#{window_name}.#{pane_index}', or
#   tmux display -p '#{session_name}:#{window_name}.#{pane_index}'
