setMnemonic doubt

[miguel lisboa]

i used:

button.setMnemonic(10);  

in order to reach the effect of clicking it with pressing ENTER key instead, but it only works with ALT+ENTER combination

i read the following from API:

Sets the keyboard mnemonic on the current model. The mnemonic is the key which when combined with the look and feel's mouseless modifier (usually Alt) will activate this button if focus is contained somewhere within this button's ancestor window.

My Q: how can i arrange things so that it works by just pressing ENTER?

        botao.getActionMap().put("pressed", new AbstractAction() {
 
public void actionPerformed(ActionEvent e) {
