Listen to any PDF instead of reading

I just learnt below stuff so lets share it.

You can listen to any PDF instead of reading with Adobe Reader 7.0 or 6.0, and the short cut is:

Ctrl+shift+b - to hear the entire Document
Ctrl+shift+v - to hear the page
Ctrl+shift+c - to resume
Ctrl+shift+e - to stop Open any PDF File

What next? you should test it.
