text input/video array

Say I have a blank string for input of user text. Say I have an array of video files.

Now say I want to link each of these mov files to their respective key. When the user types something out and presses Enter, a new mov file if created, which consists of all that concatenated info. I've searched some previous topics on this issue, but I'm still unable to get this to work. Full code so far below:

import processing.video.*;

String tempWord="";
Movie[] movies= new Movie[3];

void setup()
{
size(640, 480);
movies[0]= new Movie(this, "A.mov");
movies[1]= new Movie(this, "B.mov");
movies[2]= new Movie(this, "C.mov");
}

void draw()
{
background(0);
textAlign(CENTER);
text(tempWord, width/2, height/2);
image(movies[0], 0, 0);
}

void movieEvent (Movie m)
{
m.read();
}

void keyPressed()
{
if (key==ENTER)
{
    tempWord="";
    if (key=='a')
    {
      movies[0].play();
    }
}
else
{
    tempWord+= key;
}
}

If key == ENTER, it cannot be key == 'a'. The test on 'a' is not at the right place.
Beside, I don't get the " a new mov file if created, which consists of all that concatenated info" part.

Ack. I basically just meant that each key is associated with a video. When you type something in and hit enter, all that text is returned as the appropriate sequence of videos, and you wind up with a new mov file.

Where would you suggest I put that test on 'a' and all other characters?

Right now my big stumbling block is the fact that processing only occasionally returns "ArrayIndexOutOfBoundsException: Coordinate out of bounds!" Even though I've made zero changes to the code. Um...why is this?

I don't see how you can have an ArrayIndexOutOfBoundsException on the code you show, since you access only the index 0...
And you can test 'a' at the same level than ENTER, not inside it (key cannot be both ENTER and 'a').
Note that you can map characters to numbers: key - 'a' will give 0 for a, 1 for b, etc. Beware of other chars!
