Thanks Jan, Clinton Roy and clacke.

I'm glad you are finding the series useful.

I had known of Readline's existence for years, and that there were some features that might be useful, but had never spent the time to find out what it could do. I am most surprised at the amount of work that has gone into this library and the great features it offers.

I expect to be able to get another couple of shows from it before I'm finished, and there's scope for others to contribute too if they work out cool things to do with it!
