[senco-forum] Diagrams on laptops

I've just been reading "Dyslexia in Secondary School" by Cogan and Flecker  
and it mentions the ability to use a "special stylo" to draw diagrams on the  
screen of a laptop by clicking "insert - ink drawing' on the normal word  
processing programme. Does anybody know anything about this please? I can't find  
it in my word programme.
