Source Tmux Config

You’ve been iterating on your Tmux configuration file, and now you want to your configs in action without closing the program. But how?

Here’s the command to source an updated tmux.conf:

$ tmux source-file tmux.conf

Tmux Copy Mode

Fri, 26 Aug 2022 17:54:55 -0400

Last week we encountered a breaking change in our Tmux configuration, and briefly lost the ability to scroll with the mouse. It became an opportunity to re-learn Tmux’s copy mode, and liberate ourselves from the mouse a little more.

Enter copy mode with <prefix> [. From here, you can navigate with standard Vim commands.

ctrl-u moves you a half-page up, perfect for wading through test failure backtraces.
