ActionScript 2.0 :: Recording Key Presses In An Interval?

I am creating a program where I am randomly flashing a series of words, and I would like to be able to record when someone has hit the "x", even very briefly, when looking at the word.I have inserted all of my code below, but I have difficulty with the section in bold. Everything is working except that in order for the "x" key press to be counted, it must be held down as the words actually change. Is there any way to have it record that the "x" is hit even if it very briefly? Whenever I try to use the key listener function, it does not work with my loop for displaying text.

stop();
var tempvariable = new Array();//array create variables stored in Flash to be saved for later display
var itemarray = new Array(); //This is the array to hold the Words that need to be randomly shuffled

[code]....
