Hello,

This module may give an idea - https://apps.odoo.com/apps/modules/8.0/wct_keyboard_shortcuts/

Use Above  module code.

$.ctrl('D', function() {
$('a[data-section="other"]:contains("Duplicate")').each(function() {
if($(this).parents('.oe_sidebar_print').length == 0){
$(this).click();
}
});

});

you can write your function similar to this.
