If a key is red that means it is not pressed, if a key is green that means it is pressed, if a key is blue that means it is pressed and shift is pressed, if a key is grey that means scratch cannot detect that key being pressed. If you click "See Inside"you should see a custom block labeled "Position Keyboard", you can change its X, Y, and size values to change where the keyboard is on the screen, and how big it is.
