Hi Brian,
Thank you for your book.
Recent versions of tmux has support for OSC 133 escape codes that allows terminals/tmux know boundaries of shell prompts and command output. They are very handy to jump between command output in tmux copy-mode. Unfortunately they are tricky to configure, could you please add a chapter on this?
Commands next-prompt/previous-prompt with and without -o flag.

Thanks,
