Page 41, status-left-length misdocumented In the table of settings on p41, "status-length-left" and "status-length-right" are documented. The actual names appear to be "status-left-length" and "status-right-length". Page 53 tmux 3.5a added 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. Page 59, "use save-buffer to copy text" This text: There is no direct way to use save-buffer to copy text into a buffer and specify the name at the same time. This is a mistake, not in the claim, but in the command given. It's true that you can't copy text into a buffer while naming the buffer, but you wouldn't use save-buffer to do that, right? save-buffer writes a buffer to a file on disk. It's copy-selection that copies text into a buffer, and it doesn't take -b option, which is what this is meant to get at. Page 61, top of the page, the code should be: # Detect the display server protocol and set clipboard commands if-shell '[ "$XDG_SESSION_TYPE" = "wayland" ]' \ 'set -g @copy_command "wl-copy"; \ set -g @paste_command "wl-paste -n"' \ 'set -g @copy_command "xclip -sel clip -i"; \ set -g @paste_command "xclip -sel clip -o"' # Prefix Ctrl-C takes what's in the buffer and sends it to system clipboard # via the command stored in the variable. bind C-c run-shell 'tmux save-buffer - | #{@copy_command}' # y in copy mode takes selection and sends it to system clipboard via the # command stored in the variable. bind -T copy-mode-vi y send-keys -X copy-pipe-and-cancel "#{@copy_command}" # Prefix Ctrl-v fills tmux buffer from system clipboard, then # pastes from buffer into tmux window bind C-v run-shell '#{@paste_command} | tmux load-buffer - \; paste-buffer'
