mem - how did you get your example to be in colour?

to get the syntax coloring, from the ide edit menu, select 'copy for forum'

Serial.print("x ");
Serial.print(x);
Serial.print(" y ");
Serial.print(y);
Serial.print(" z ");
Serial.println(z);

I think beginners find that ungainly.
There has got to be a better way that does not look scary.
