Criando Teclas de Atalho

E ae pessoal, queria uma ajuda pra criar uma tecla de atalho para um botão.

Dei uma pesquisada e usei isso aqui:

btNovo.setMnemonic(KeyEvent.VK_N);

E isso gera o atalho Alt + N para chamar o botão, porém estou procurando pra fazer Ctrl + N.

Tem como fazer isso?

Valeu

este aqui, funciona com o enter...

private void jTletraKeyPressed(java.awt.event.KeyEvent evt) { // TODO add your handling code here:

if (evt.getKeyCode() == 10) {
JOptionPane.showMessageDialog(null, "ENTER!", "Letra ja dita", JOptionPane.INFORMATION_MESSAGE);

}
}

public void keyReleased(KeyEvent e) {
}

public void keyTyped(KeyEvent e) {

}[code]

o 10 é o codigo ascii, do enter...
da para usar varias, coisas, ja para usar junto com o ctrl, nao sei... agora... mas uma tecla so, ja da de fazer... com alt tambem conheço.

segue uma imagem da tabela ascii, no atachement

O PROGRAMA É BEM INTERESSANTE. AQUI MUDEI PARA FUNCIONAR.... COM CONTROL F E COM A LETRA A... É SÓ MUDAR ALI QUE MUDA MESMO. JA O SHIFT D, tem que clicar no botao do shift d, para funcionar, nao entendi muito bem o porque, mas aí responde.

aqui tudo com control, as vezes funciona um ou outro, depende o botao que clica... mas se quiser uma função só, acho que não vai haver problemas, vale o teste. valeu...

funciona tudo normal, se focar tudo para a janela…

InputMap inputMap = jb1.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW);

:shock:
