(define-remapped-keys) With Multiple Key Sequences

Hello all,

I have just started playing with (define-remapped-keys) and was 
wondering if there is a way to get multiple keys sequences in a program 
to do one thing. Basically I want to do something like this:


(define-remapped-keys

     '(("(firefox|Chrome)"

      (("C-x" "C-h")   . "C-a"))))

I envision that me pressing C-x, then C-h, will allow firefox to do the 
C-a key binding. Is there a way to do this and I just don't know the 
syntax, or is this impossible?


Thank you very much for your help!,
