you can define own keys processors (mainframe jframe instance)

actionmap actions = ((jcomponent)mainframe.getcontentpane()).getactionmap(); inputmap inputs = ((jcomponent)mainframe.getcontentpane()).getinputmap(jcomponent.when_ancestor_of_focused_component);  action a=new abstractaction() {     public void actionperformed(actionevent e) {         //call action code here     } }; actions.put("myaction", a);  inputs.put(keystroke.getkeystroke(keyevent.vk_enter, keyevent.ctrl_down_mask), "myaction");
