Listening to the PDF

This is nice and cool info from one of my colleagues. If you use Acrobat Reader 7.0, you can listen to the PDF. The following are the shortcuts:
ctrl + shift + b - To listen to the entire document
ctrl + shift + v - To listen to the current page
ctrl + shift + e - To Stop
ctrl + shift + c - To Resume

Very cool, isn't it. Try it out!!
