@Api developer :
Below is jqyery code snipped it used to trigger an event when a key is
pressed (down).
$(document).keydown(function(e) {
//If escaped key is pressed.
if (e.keyCode == 27) {
//Some functions.
}
});
Dont't know exactly if the below code will work on not.
google.visualization.events.addListener(pie, 'keydown', function (e) {
alert(e.keyCode);
});
