C++ Builder adding Ctrl + A option

I have been trying to add Ctrl + A option in Builder 6 but I am out of ideas. I have tried using

(Shift.Contains(ssCtrl))

and add 'a' and 'A'. And I am kinda out of ideas how to look at this because as far as I remember Ctrl + C and Ctrl + V are added differently since they are default options. Or so I have been told.
