[rt-users] Callback lesson please please

[Roy El-Hames]

Hi There;
RT-3.6.4

Can someone give me few lines on how to use callbacks to customise RT, 
I've installed shredder for the only purpose of learning how it used 
callbacks, but it just added to my confusion , I want to add the 
CreateChildTicket callback as described in the Wiki but I am failing to 
see any buttons in my display ..
Can anyone help please??

Regards;
Roy
