There's a difference between keeping track _as you read_ and placing a marker _when you stop reading_. You may not agree, but the facts are the facts. ----- Original Message ----- From: "Anthony" <anthony.gough@xxxxxxxxxxxxxx> To: <bookport@xxxxxxxxxxxxx> Sent: Friday, September 08, 2006 12:27 PM Subject: [bookport] Re: Does book port support undo I do know the key I pressed and I have read the manual, I accidentally held down the 2 key for too long. As for the book port constantly keeping track of where it is I would assume it does that anyway because it can resume from where it left off. I appreciate the bookport doesn't have huge processing power but I am sure the position could be stored in say a couple of bytes, It must have pointers to where it is in a file or how does it function? I am sorry but I don't agree that it would introduce a huge processing overhead, I remember the days when people wrote quite complex programs on 8 bit home computers with small amounts of memory. I was just putting it forward as an idea as on my plextalk talking book machine I find undo useful at times. Anthony
