To use this configuration.

You can download this .tmux.conf into your HOME directory or create .tmux.conf in your HOME directory ($HOME) and copy this configuration into it.

Tmux uses prefix before executing your commands. I personally set prefix to Ctrl-s because it's easy to type.

1. Splitting pane,

• `prefix' + v splits window vertically
• `prefix' + s splits window horizontally

3. Moving between panes, I'm using vim styled keybindings, so hjkl maps to left/down/up/right

• `prefix' + l move focus to right of current pane
• `prefix' + h move focus to the left of current pane
• `prefix' + j move focus to the beneath of current pane
• `prefix' + k move focus to the above of current pane
