  "description": "List the variables tmux hands to processes it starts, for the server or for one session, and whether each is set or marked for removal. Values are withheld: a tmux server inherits the environment of the shell that started it, tokens and keys included. A value is returned only for a name the operator listed in LIBTMUX_ENVIRONMENT_VALUES at startup, and is then returned in clear. This is not the environment of anything already running: a pane started before a change keeps what it was given. Read the tmux environment; accepts no client-supplied executable input. Values are withheld unless the operator allowed the name.",
