I got to know this tools from AMIS technology blog when they told abt that, although my job is focus in operation but something in order to give some detail on how new process /instruction i need to give some hand on to my engineer.
So i goto the link provided and download it http://technet.microsoft.com/en-us/sysinternals/bb897434.aspx . let's see how it work
There is actually 3 key to activate it , first i use the default which is Ctrl-1 , it will zoom the existing page
When Ctril-1 is keyed - It will zoom the page and allow us to move versus mouse
When Ctril 2 is keyed , movement will be stop and let's start some highlight and drawing..:)
it work the same in mouse when we left click it will activate Drawing Mode and right click will go back in Zoom Mode , follow the sequences.
Guess what i notice ,this tools just publish on 28 May 2008.
