  TPU and embedding escape sequences? 
 The Question is:
 
I need to embed an escape code sequence into a text file that will be printed.
What are the keystrokes necessary to insert the &lt;ESC&gt; key into the text file
 (using tpu)?
 
 The Answer is:
  The ^V command in TPU can be used to insert control characters into the
  text (with the exception of control characters like ^Y, ^O, ^S, ^Q etc
  which are trapped by the terminal driver). For an ESCAPE character, use
  ^V followed by ^[.
