[MacDV] dias and idvd

[John Kiss]

Sorry for these last 2 weird posts of yesterday. I was trying to get  
the dictionary definition of 'dias' by using a keystroke combination  
that I couldn't quite remember and tried a few alternatives.  
Obviously that didn't work. I think I hit command-shift-D instead of  
command-control-D
