How to programmatically press a key?

How can I programmatically press a key in Matlab? I click outside of the Matlab environment by the java.awt.Robot command, but after that I would like to press some keys (e.g. type "Hello"). I tried the keyPress(KeyEvent.VK_H) command found online, but that does not seem to work. Any suggestions?

This is the code I tried:

import java.awt.Robot;

import java.awt.event.*;

robot = Robot();

robot.mouseMove(1100,54);

robot.mousePress(InputEvent.BUTTON1_MASK);

robot.mouseRelease(InputEvent.BUTTON1_MASK);

robot.keyPress(KeyEvent.VK_V);

You also need to send the key release event.

Thanks! That solves the problem.
