how to write code for keyboard inputs

I want write matlab code for some keyboard input.

I have assigned a variable called "P" and want to write codes inside P when P=1 and P=2 and P=3 and P=4.

when P=1 (should be written code for automatically pressing "shift+f5")

when P=2 (should be written code for automatically pressing "esc")

when P=3 (should be written code for automatically pressing "right arrow key")

I have written code for automatically mouse left click event when p=4

             if(P==7)     % mouse click event

            mouse.mousePress(InputEvent.BUTTON1_MASK);
            mouse.mouseRelease(InputEvent.BUTTON1_MASK);

        end

could you please give me the solution for this

thanks...

Does this have to do with the Java Robot class, or does it have to do with keyboard shortcuts?
