Adding public method and small change to Keypad.h

bool isPressed(char keyChar, bool bypassStateChange = false);
bool isHolding(char keyChar);
bool wasPressed(char keyChar);

Adding methods to Keypad.cpp

/// @brief Check if a particular key is pressed
/// @param keyChar The key you want to check
/// @param bypassStateChange Disregard the state check, useful if you want to continuously know if this key is being held down without waiting for the HOLD state to be met.
/// @return True if the key has been pressed and the state has been changed, unless the state has been bypassed, then simply True as long as the key is pressed.
bool Keypad::isPressed(char keyChar, bool bypassStateChange = false) {
	for (byte i=0; i<LIST_MAX; i++) {
		if ( key[i].kchar == keyChar ) {
			if ( (key[i].kstate == PRESSED) && (key[i].stateChanged || bypassStateChange) )
				return true;
		}
	}
	return false;	// Not pressed.
}

/// @brief Check if a particular key was pressed and reset its state so that doesn't repeat until pressed again.
/// @param keyChar The key you want to check
/// @return True if the key has been pressed and False until it has been released and pressed again
bool Keypad::wasPressed(char keyChar) {
	for (byte i=0; i<LIST_MAX; i++) {
		if ( key[i].kchar == keyChar ) {
			if ( (key[i].kstate == PRESSED) && key[i].stateChanged ){
				key[i].stateChanged = false;
				return true;
			}				
		}
	}
	return false;	// Not pressed.
}

/// @brief Check if a particular key is being help
/// @param keyChar The key you want to check
/// @return True if the key is being held down
bool Keypad::isHolding(char keyChar) {
	for (byte i=0; i<LIST_MAX; i++) {
		if ( key[i].kchar == keyChar ) {
			if ( (key[i].kstate == KeyState::HOLD))
				return true;
		}
	}
	return false;	// Not pressed.
}

Just useful for quickly and easily determining that a specific key has been pressed and/or held. With or without state.

Purpose:
I'm using the keypad to also double as a directional pad to act as WASD input.

Hi @escfoe2. "Keypad" is a 3rd party library not maintained by Arduino, so this feature request is off topic for this issue tracker. You can submit it to the repository of the "Keypad" library if you like.
