I have always used transparencies to present in conferences, but right now I decided to do power point presentation. So for this I need to take a "snapshot" from the equations I have in my arxiv papers and paste them into power point. Can you guys tell me how to do the "snapshot"? I know I have done that when I have defended thesis, but I forgot how to do that (my girlfriend guided me through back then). So can you guys remind me of the procedure? Another thing: right now I am using a different laptop than I used back then, so it is possible that snapshot tool was on my previous laptop but not this one. So the question is: 1) How to find out if I have snapshot tool in my current laptop? 2) How to download it if I don't have it? I prefer to make that download free since I don't have much money 3) Once I have snapshot, how to use it? What bottoms to push? What command to look for at the top of the screen, etc? I am really bad in computers I need a detailed description.
