   Now the call 
 
-  @{ML_response_fake [display] "ackermann (4, 12)" "\<dots>"}
+  @{ML_response_fake [display,gray] "ackermann (4, 12)" "\<dots>"}
 
   takes a bit of time before it finishes. To avoid this, the call can be encapsulated 
   in a time limit of five seconds. For this you have to write:
 
-@{ML_response [display]
+@{ML_response [display,gray]
 "TimeLimit.timeLimit (Time.fromSeconds 5) ackermann (4, 12) 
   handle TimeOut => ~1"
 "~1"}
