Quickly edit and reload #tmux configuration
When you are playing around with your tmux config you often need to repeatedly open .tmux.conf file and then source it into the current tmux session.
To make things a little faster, add the following to your .tmux.conf:
bind-key r source-file ~/.tmux.conf \; display-message "~/.tmux.conf reloaded"
bind-key M split-window -h "vim ~/.tmux.conf"
Now you can quickly open the tmux config in tmux pane using <prefix> followed by shift + M, edit your configuration, and save when you done. To reload the tmux configuration use <prefix> followed by r.
** <prefix> is C-z for hashrocket's dotfile project (dotmatrix), if you are using tmux default configuration it would be C-b
