New Subject - tips and tricks

I  have started to  change things around a bit. Under the main heading you will find  useful  tips and tricks. If you click on it, it will  take you there. I will add a  new  one each week.  Some  of  it I have found on  the  net, others is just from my own observations. I  don't know if they are right  or wrong, so  read  it and make  your own conclusions. If  you  have any to  share  please let me know.
