# Afterwards, consult the tmux cheatsheet: https://tmuxcheatsheet.com/

# unbind the default key commands and use Ctrl-a instead since they're
# closer to each other on a qwerty keyboard
unbind C-b
set -g prefix C-a

# ctrl+left/right cycles thru windows
bind-key -n C-right next
bind-key -n C-left prev

# open a man page in new window
