My tmux configuration. Enables colours, uses backtick as a prefix (double backtick to write an actual backtick). Ctrl+d and Ctrl+e for split panes (a la hyper.js)

.tmux.conf

#enable colours
set -g default-terminal "xterm-256color"

#add ` as prefix
set-option -g prefix2 `

# double tap ` to get a real `
bind ` send-keys `

# split panes using | and -
bind C-d split-window -h
bind C-e split-window -v

# reload config file (change file location to your the tmux.conf you want to use)
bind r source-file ~/.tmux.conf

# Enable mouse mode (tmux 2.1 and above)
set -g mouse on
