A word written to a raw terminal's look is listed, as in normal mode

A new Tty is in raw mode, where a right click is its program's, and a
look written to it over 9P did nothing for that reason. The look file is
no keyboard input: over 9P a plain word is listed in a +Search pane and
read back whatever the terminal's key mode.
