Thanks for your attention Walter Roberson.

The problem still countinues. When i type the code below :

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.KeyEvent;
keyboard=Robot;
>> keyboard.keyPress(KeyEvent.VK_DEAD_ABOVEDOT VK_O);
??? keyboard.keyPress(KeyEvent.VK_DEAD_ABOVEDOT VK_O);
|
Error: Unexpected MATLAB expression.

gives this error and also

>> keyboard.keyPress(KeyEvent.VK_SHIFT VK_SLASH)
??? keyboard.keyPress(KeyEvent.VK_SHIFT VK_SLASH)
|
Error: Unexpected MATLAB expression.

keyboard.keyPress.KeyEvent.VK_DEAD_ABOVEDOT;
keyboard.keyPress.KeyEvent.VK_O;

The KeyEvent method takes only a single keycode.

this is the wrong syntax, though...
it should read

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.KeyEvent;
kbd=Robot; % <- don't use KEYBOARD as a var...
kbd.keyPress(KeyEvent.VK_DEAD_ABOVEDOT); % <- see below...
kbd.keyPress(KeyEvent.VK_O); % <- this works...
% however, this does NOT always work...
kbd.keyPress(KeyEvent.VK_DEAD_ABOVEDOT);
%{
??? Java exception occurred:
java.lang.IllegalArgumentException: Invalid key code

Thanks for your attention Walter Roberson and us
i'm using MATLAB R2009b but when i type given code below by yours, it still gives me error.

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.KeyEvent;
kbd=Robot;
kbd.keyPress(KeyEvent.VK_DEAD_ABOVEDOT);
??? Java exception occurred:
java.lang.IllegalArgumentException: Invalid key code

at sun.awt.windows.WRobotPeer.keyPress(Native Method)

at java.awt.Robot.keyPress(Unknown Source)


kbd.keyPress(KeyEvent.VK_O);
>> o


kbd.keyPress(KeyEvent.VK_O) works but,
kbd.keyPress(KeyEvent.VK_DEAD_ABOVEDOT) doen't work on my computer
