My current tmux setup. This has a long way to go but it is good to get something here if I ever need to set tmux up again.

# Allow scrolling with the mouse wheel
set -g mouse on

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

# Highlight active window
set -g window-status-current-style bg=red,fg=white,bold

# Faster command sequences
set -s escape-time 0

# Change to bind seq to Alt-f
set-option -g prefix M-f

# Change navigation between tables
bind-key k next-window
bind-key j previous-window

# Make sure there is colour in the terminal
set-option -g default-terminal "tmux-256color"
set-option -sa terminal-overrides ",xterm-256color:RGB"
