Instructions

This tabular form allows you to navigate through the fields by holding down the control key and using the arrow keys - as described here: https://forums.oracle.com/forums/thread.jspa?threadID=2526996&tstart=0

  1. Give the tabular form a static ID. I called this one arrow-tabular.
  2. Create a new dynamic action:
    Event: Key Down
    Selection Type: jQuery selector
    jQuery Selector: #arrow-tabular input
  3. True Action: Execute JavaScript code
    Code:
    
    var baseSelector = '#arrow-tabular input[type!="hidden"]';
    
    if(event.ctrlKey){
        event.preventDefault();//i.e. stop scrolling
        switch (event.keyCode) {
            case 37:
                //left
                var prevElIndex = $(baseSelector).index(this.triggeringElement)-1;
                $(baseSelector + ':eq(' + prevElIndex + ')').focus();
                break;
            case 38:
                //up
                var name = this.triggeringElement.name;
                var row = $x_UpTill(this.triggeringElement,'TR');
                var prevRow = $(row).prev();
                $('input[name="' + name + '"]', prevRow).focus();
                break;
            case 39:
                //right
                console.log($(baseSelector));
                var nextElIndex = $(baseSelector).index(this.triggeringElement)+1;
                $(baseSelector + ':eq(' + nextElIndex + ')').focus();
                break;
            case 40:
                //down
                var name = this.triggeringElement.name;
                var row = $x_UpTill(this.triggeringElement,'TR');
                var nextRow = $(row).next();
                $('input[name="' + name + '"]', nextRow).focus();
                break;
        }
    }
    
    
  4. It is important to update the dynamic action and specify the Event Scope as Dynamic, so that and additional rows that are added are still affected.
