Crt_gate() is the event loop: it monitors the keyboard; it       implements  a  vi-style cursor move for the keys hjkl, and       possibly, for the arrow keys; if  return  is  pressed,  it       sends an Event object with kind 1 and an array with column       and row position; if control-D is  pressed,  gate  returns       reject; any other key is sent on as an Event object with a       string containing the key character.       A CLineOut object implements a LineOut object on a  curses       screen.  Incoming strings should not exceed len bytes.       A  CButton  object  implements a Button object on a curses       screen.  If it receives a  matching  text,  it  sends  it.       Additionally,  if it receives a position event, e.g., from       a Crt object, and if the coordinates are within  its  win-       dow, it sends its text on.SEE ALSO       Event(4)                            local: ats                          1
