Not sure if anyone recalls the reference, but in a Simpsons episode many years back, Homer Simpson used a toy bird to hit his keyboard every couple of minutes to perform a very simple function at work so that he didn't have to be by his computer (or maybe it was so he could nap, I don't recall). I am looking for a similar trick (minus the toy bird) for an online course I am taking that has a timer that I am required to be "reading" during this time and the timer stops when the page goes idle for a minute or two. I was thinking that if I could hit the space bar or somehow cause the cursor to move every 30 seconds, I could keep the timer going, even while I was sleeping. Any ideas on how I may be able to set up my Mac to make it appear that I am on the page and doing something while I am away?
