Re: block <ctrl><alt><del> and <alt><tab>

<shift><f4> or <alt><f4>? Anyway, you could try to block with Javascript the <alt> key, which is common among all your options (or <alt> and <shift>). There's a key map on Javascript that references each keyborad key with a variable. Just do something like onKeyPress('var') = ''. I don't remember the exact code but a google search will do fine. PS: I don't know if you know this, but it's impossible to prevent keystrokes with PHP (since it's server side), unless you go really crazy and exec(); a program to do so. -- Julio Nobrega.
