Hi @Rohith Happy to see that your problem is solved now, you are welcome !

Here's the solution. You have to do it in Javascript. Ensure jQuery is loaded in your web pages (even the IFRAME/FRAME ones) and then apply this code: <script type="text/javascript"> $(document).ready(function(){ // Disable backspace key except in fields. $(document).keydown(function(e) { var elid = $(document.activeElement).is('INPUT, TEXTAREA') ; if (e.keyCode === 8 && !elid) { if(e.ctrlKey) { window.history.back(); } else { // disable backspace e.preventDefault(); return false; } } }); }); </script> SOURCE: http://stackoverflow.com/a/17278620/105539

Ahh hadn't thought of that. I didn't realize tooltips would activate either on a disabled control. I'll give it a try.
