wlterm: the native Wayland terminal emulator

Recent experience suggests that it's pretty difficult to explain to people how to use it (1) over the telephone and (2) from memory of how it actually behaves, especially when a normal menu would be obvious enough. There's also the issue of navigating through a keyhole when the door is already open, but I know that the other extreme is full-screen menus, and that menu navigation can also be an exercise in applying finely tuned motor skills.
