I am interested in simulating a keyboard input using .m code.
How would I go about simulating typing and other keyboard inputs?
Similar to this, but with the keyboard instead of the mouse.

ying xing FENG commented "It works for text. But not for other active windows other than Matlab. For eg. on screen key borad. Any idea? "

Does anyone know how to emulate a ; or a \ ? I can emulate keystrokes, but the ‘VK_OEM_1´input to keyPress is undefined.
Thanks

Haha, nice.
Why does SimKey.keyPress(KeyEvent.VK_w); now work for undercase w? Is there a full list of keyboard inputs I can reference?
What is "VK" referencing to?

KeyEvent.VK_W is the [W] key - there is no upper or lower case *key*! You need the [Shift] key to create uppercase characters:
robot.keyPress(java.awt.event.KeyEvent.VK_SHIFT)
robot.keyPress(java.awt.event.KeyEvent.VK_W)
robot.keyRelase(java.awt.event.KeyEvent.VK_W)
robot.keyRelease(java.awt.event.KeyEvent.VK_SHIFT)
Remember: It is only a robot and it s(t)imulates the keyboard...

Hi Paulo,
regarding"execute my code and Matt code on the command line of matlab (not in a script) :)"
I am going to kill an running script through simulating Ctrl+C which is written as a function like this:
import java.awt.Robot; import java.awt.event.*; SimKey=Robot; SimKey.keyPress(java.awt.event.KeyEvent.VK_CONTROL); SimKey.keyPress(java.awt.event.KeyEvent.VK_C); SimKey.keyRelease(java.awt.event.KeyEvent.VK_CONTROL);
how can I call it? when I call this function it does not work? Thanks, Ali
