Default: Don’t follow.press q or CtrlC to quit.press F5 to toggle tree/list view. Default: list view.press ↑ and ↓ to navigate between containers.press or - to toggle child cgroup foldingclick on title line to select sort column / reverse sort order.click on any container line to select it.Additionally, for supported container types (Currently Docker, LXC and OpenVZ):press a to attach to console output.press e to open a shell in the container context. Aka ‘enter’ container.press s to stop the container (SIGTERM).press k to kill the container (SIGKILL).press c to checkpointing the container(OpenVZ only now – run ‘vzctl chkpnt CTID’)
