javascript help with variables

With some help, I wrote this javascript.

I don't understand how to add more than one variable to a variable, I need for there to be several "keycodes," not just one. Other than that, the script works fine.

op here, thanks a lot. I wasn't familiar with how to make variable arrays.

With the array variables, it seems like your method is the only way to make the script work, my "if else" way of doing it doesn't work with the variable arrays. Could somebody explain why? Also, your way of doing it is cryptic to me. I don't understand what "i" does, I need to go read up on it.

thanks again, I really appreciate it.
