Nesting Remote tmux sessions inside our local tmux

Para que esto funcione, tmux debe de estar instalado en el servidor SSH y ambos archivos de configuración deben de estar en él.

# Session is considered to be remote when we ssh into host
if-shell 'test -n "$SSH_CLIENT"' \
    'source-file ~/.tmux.remote.conf'

# We want to have single prefix key "C-a", usable both for local and remote session
# we don't want to "C-a" + "a" approach either
# Idea is to turn off all key bindings and prefix handling on local session,
# so that all keystrokes are passed to inner/remote session

# see: toggle on/off all keybindings · Issue #237 · tmux/tmux - https://github.com/tmux/tmux/issues/237

# Also, change some visual styles when window keys are off
bind -T root F12  \
