How to set Shortcut keys for button in Apex

Question

Hi
Could anyone help me on how to set shortcut keys for buttons in Apex.
I need to use say ALT + S to submit the page.
The following thread pertaining to HTML DB refered to use ACCESS key. but that couldnt work in my case.
Re: operation of the app. with the keyboard
Any pointers on achieving this would be helpful.
Thanks

Hi Vijay,
I’m afraid you must do it using javascript key listener. You can’t use action() on template based buttons because they are actually not HTML buttons but images with hyperlink.
Key listener checks which key has been pressed down and invoke some JS function. For example, write this code in page header:
<script>
document.onkeydown=keyCheck;
function keyCheck(e){
     var KeyId = (window.event) ? event.keyCode : e.keyCode;
     switch(KeyId){         
          case 113:
               doSubmit('SAVE');
               break;                    
          case 118:
               alert('Hello');
               break;
</script>
This script will submit page with request 'SAVE' if you press F2 or will show alert message if you press F7. Modify it to your issue.
