Custom Button on the RF screen

Hi Sdn,

I got a new requirement of adding a button on the RF Menu screen.

Right now we copied all the standard buttons like F1,F2,F3 and F4.

And we want to add one more button on the screen Change Password.

Once the user clicks on the chnage password button we want to call an URL in the same screen where user can change the password.

Can any one tel me if i want to add an button on the RF Menu screen what is the procedure.

The screen code is in HTML java script language.

Thanks

Naresh
