program keys?



I have programmed my TI89 to 1/cos(x)->sec(x), but I
would like to program the keyboard so that pressing
alpha (the purple key) then the z key would output
"sec(" on the screen, is this possible?

One other thing, I have programmed
x!/(x-y!)y!->c(x,y), but can I program it so "4c3"
could do the same thing? I could save some key types
that way,
ie: "4","alpha","c","3"
instead of "alpha","c","(","4",",","3",")"

Thanks for help on either problem.
