Thank you, Chris Johnson, for initially showing me what tmux was all about, and for pointing me in the right direction with my initial questions. It completely changed how I work, and its what motivated me to share this amazing tool with everyone.

Thank you, Susannah Pfalzer, for working with me again. You challenged me once again to grow as an author, and this book and I are better for it.

Thank you, Alessandro Bahgat, Jacob Chae, Jeff Holland, Michael Hunter, Sean Lindsay, Lokesh Kumar Makani, Nick McGinness, Stephen Orr, Peter Perlepes, Charley Stran, and Colin Yates, for reviewing this book.

Your mouse is slowing you down.

When it was first introduced, the mouse created a new way for people to interact with computers. We can click, double-click, and even triple-click to open documents, switch windows, and select text. And thanks to trackpads, we can even swipe and use gestures to interact with our applications. The mouse, along with graphical interfaces, made computers just a little easier to use for the average person. But theres a downside to the mouse, especially for programmers.

As we build software, we work with multiple programs throughout the course of our day. A web developer, for example, might have a database console, a web server, and a text editor running at the same time. Switching between these with the mouse can slow you down. It may not seem like much, but moving your hand off of the keyboards home row, placing it on the mouse, locating the pointer, and performing the task can eat up time and break your focus. And it can also induce strain on your wrist, arm, or shoulder. That repetitive movement of reaching for your mouse can cause some serious discomfort if youre not careful about how you hold that mouse.

Using tmux, you can create an environment like this, right in your terminal, managed entirely without a mouse:
