In addition to clicking on the SDK display, you can use the computer keyboard to activate the SDK’s soft keys and enter information into the SDK.
You can use your keyboard to enter multiple, simultaneous button presses (button “chording”). In a game MIDlet, for example, if the user presses and holds the up arrow button, the game target will move up. On the mobile device, if the user continues to hold the up arrow button and also presses and holds the right arrow button, the game target will move diagonally up and to the right.
In the SDK, the PC keyboard limitations might cause the MIDlet to behave differently. If you press and hold only one PC keyboard button, the target in the SDK behaves in the same way as on the mobil device. But if you press and hold, for example, two keyboard buttons at the same time, the target might behave differently, depending on the PC keyboard and the MIDlet in question.
You can use the mouse to click one key in the SDK device, in addition to the key you are pressing on your PC keyboard.
