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.
Thanks,
Kevin

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

Don't forget to release the VK_C
