I tried to adapt your KeyEvent to get "matching double quotes"
on my Macintosh system:

Item[KeyEvent["\"",Modifiers->{Command,Shift}],
     FrontEndExecute[{FrontEnd`NotebookWrite[FrontEnd`SelectedNotebook[],
       "\"\"",After],
             FrontEndToken["MovePrevious"]}]]

but it does not seem to work. What am I doing wrong?
