# C-b is not acceptable -- Vim uses it
bind-key C-b last-window

# Start numbering at 1
set -g base-index 1

# Allows for faster key repetition
set -s escape-time 0

# Set status bar
set -g status-bg black
set -g status-fg white
set -g status-left ""
set -g status-right "#[fg=green]#H"

# Rather than constraining window size to the maximum size of any client
# connected to the *session*, constrain window size to the maximum size of any
# client connected to *that window*. Much more reasonable.
setw -g aggressive-resize on

# Allows us to use C-a a <command> to send commands to a TMUX session inside
# another TMUX session
bind-key b send-prefix

# Examples
# --------

# Activity monitoring
setw -g monitor-activity on
set -g visual-activity on

# Example of using a shell command in the status line
set -g status-right "#[fg=yellow]#(uptime | cut -d ',' -f 2-)"
