    'set -g default-terminal "tmux-256color"' \
    'set-option -g default-terminal tmux'

# terminal overrides, because I'm smarter than ncurses
# truecolor! (in normal and nested sessions)
set -ga terminal-overrides ",xterm-256color:Tc,tmux-256color:Tc"
# italics!
set -ga terminal-overrides ',xterm*:sitm=\E[3m'
# cursor shape?
