Calling server-side code from client-side

Hi, 
I´m implementing some shortcut functionality in my web forms and wanna know where i can find something that explains, for example, how to call the handler event "onclick" of a button. I´m using this library to add shortcuts to my controls:
http://www.openjs.com/scripts/events/keyboard_shortcuts/
 
And I want to "link" some key combination for the event handlers of the controls.
Does anybody knows?
 Thanks.

You could attach an AJAX event to the Javascript shortcut event handler so, for example, the shortcut function will trigger a button click which in itself is registered for an AJAX postback.  I tested it and it works...

<script>
shortcut("Ctrl+Shift+X",function() { 
 
document.getElementById("Button1").click(); 
});
</script>
 

<asp:ScriptManager EnablePartialRendering="True" ID="ScriptManager1" runat="server" />

<asp:UpdatePanel ID="up1" runat="server">

<ContentTemplate> 
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" /> 
</ContentTemplate>

</asp:UpdatePanel>

javiguillen, 
thank you for the reply. It really works, but once per refresh. I wanna know what´s going on, because it executed once and after doesn´t work any more. I guess that the AJAX library are ovewriting the events used by the shortcut method. Can you or anyone give me some help? I tried to register the script via ScriptManager.RegisterClientScriptBlock but didn´t work either, because i was thinking that if I registered the script in every refresh I will have the shortcut method linked with the right event.
 Any help will be appreciate.
 Thanks
