Keyboard.press question

Hardware Arduino Due
1

Ok, I have looked around the forum (as well as the rest of the internet), and can not figure this out..
I am using a 4 switch joystick to control 4 buttons on a keyboard. I have it work when only one direction is activated, however when 2 switches are closed, only one key is "pressed". Basically, I want to press both keys at the same time. Here is my code so far:

int jyuVal = 0;
int jylVal = 0;
int jyrVal = 0;
int jydVal = 0;
int swaVal = 0;
int swbVal = 0;
int swcVal = 0;
void setup() {
Keyboard.begin();
pinMode(13, INPUT);// JOY U? PIN
pinMode(12, INPUT);// JOY L? PIN
pinMode(11, INPUT);// JOY R? PIN
pinMode(10, INPUT);// JOY D? PIN
pinMode(9, OUTPUT);// LED IND PIN
digitalWrite(13, HIGH);// make all high for pull up
digitalWrite(12, HIGH);
digitalWrite(11, HIGH);
digitalWrite(10, HIGH);
digitalWrite(9, HIGH);

}

void loop() {
jyuVal= digitalRead(12);
jyrVal= digitalRead(13);
jylVal= digitalRead(11);
jydVal= digitalRead(10);
if(jyuVal == 0 && jylVal == 1 && jyrVal == 1 && jydVal == 1){
Keyboard.press('w');}
if(jyrVal == 0 && jyuVal == 1 && jylVal == 1 && jydVal == 1){
Keyboard.press('d');}
if(jylVal == 0 && jyrVal == 1 && jyuVal == 1 && jydVal == 1){
Keyboard.press('a');}
if(jydVal == 0 && jylVal == 1 && jyrVal == 1 && jyuVal == 1){
Keyboard.press('s');}
if(jydVal == 1 && jyrVal == 1 && jylVal == 1 && jyuVal == 1){
Keyboard.releaseAll();}

}

I would accumulate all the 4 jyxVal into a single value then use that value to index into an array of chars to use, something like this

char keys[16] = {'w', 'd', ...}; // as appropriate for each of the 16 combinations
  
keyVal = digitalRead(12);
keyVal |= digitalRead(13) << 1;
keyVal |= digitalRead(11) << 2;
keyVal |= digitalRead(10) << 3;

if (keyVal)
    Keyboard.press(keys[keyVal]);
