Tmux is a terminal multiplexer and I use it in my day to day activities. I have installed the Oh-My-Tmux. This gives some great benefits. Oh-My-Tmux maps the CTRL+A as the trigger key. Default is CTRL+B.

Tmux has a client/server model, so you can detach and then later attach back to the same Tmux session. So you can continue working from where you left off. This is a great benefit.

    tmux new-session -s MySession 
    tmux detach-session MySession 
    tmux attach-session -t MySession

You can create mutiple windows

Operation Command
Creates a new window CTRL+A C
To split the window horizontally CTRL+A ,
To view the pane number CTRL+A 1

You can create mutiple panes

Operation Command
To split the window vertically CTRL+A %
To split the window horizontally CTRL+A “
To view the pane number CTRL+A q
To change between the panes CTRL+A arrow key

These are basically the commands I use. Tmux offers much more like different modes etc.

You can see tmux in action in this video.
