When I started I used pen and paper, but you might find putting the text into a spreadsheet helpful. You will have to think about how to get the text into the cells the way you want, but once you have done that you can rearrange the columns easily. A more sophisticated approach is to learn to use grep in a text processor like BBEdit. You can get it to do things like replace characters matching a pattern, re-order strings and so on! Harry
