On key press with variables

Hi
I have 5 buttons. I want each one to be played from the keyboard with a key, but i need the specific key to each button to be a variable read from a txt file. I can load the file and store the variables but i can't pass a variable to On Keypress == variable...
any thoughts?

Thanks in advance,
Shahar Zrihen

why you need to pass it to onKeypress?
Load the variables, then add a Key listener (see Key class).
then test which key was pressed. And if it matches one from the file, do something.
