My previous reply shows a difference between humans and computers: aiming to italicise some words I pressed 'send' instead of the italicize icon. Another difference is that failure in my action gave rise to immediate error-recognition operating at a W2 level and using W3 content as its basis. Now I need to look at what I sent to see how far it is deficient because sent prematurely - again something involving W2-W3 understanding that goes beyond what a W1 computer could ever do.
