So far the previous AU documents I have read... does not worth the reading.....
I beg to differ! I learned something already this morning that I didn't know. If you hold down the Num-Lock key for 5 or more seconds it will bring up the "ToggleKeys" dialog in Windows. If you click the OK button, you will get an audible alarm each time you press the CAPS LOCK, NUM LOCK, or SCROLL LOCK keys. And a different sounding alarm when it's pressed again.
Want to turn that feature off? Hold the Num-Lock key for 5 seconds again.
It's part of the Accessibility Features of XP.
Seriously, besides that, there's a wealth of information on Sheet Sets, Dynamic Blocks and the CUI. Good stuff.
