How can I remove the keypress event listener in menu

[sten82]

Hello,

is there any possibility to remove the keypress event from menu?

Ext.create('Ext.menu.Menu', {
    width: 100,
    height: 100,
    margin: '0 0 10 0',
    floating: false,  // usually you want this set to True (default)
    renderTo: Ext.getBody(),  // usually rendered by it's containing component
    items: [{
        text: 'regular item 1'
    },{
        text: 'regular item 2'
    },{
        text: 'regular item 3'
    }]
});

This example is from the docs. If I click on any menu button and press the left key on my keyboard the complete menu disapears. Can I disable this behavoir?

Thanks in advance,
carsten
