Hi: Can't quite remember all the ground that was covered on the thread of editing files. One thing I will add because I didn't know it for ages, is that not only does keypad enter usefully serve as a shut-up-until-next-keypress command, but it also routes your reading cursor to the actual system cursor, regardless of whether or not the reading cursor is parked. I find this an invaluable command and use it a great deal. Geoff.
