Hi and Happy New Year to all
I have installed Windows with WMWare - and could not find @ on my keyboard 
My husbond showed me an Ascii table where I could find some of the signs I could'nt find on the Keyboard..
BUT the table is not the same on Mac 
To find the @ you have to use the right ALT botton and press 62 - at the Ascii table the number for @ is 64 and not 62??
Hope this will help you find some of the lost signs
