Thank you for writing and for sharing your observations and thoughts regarding our documentation.
In regards to the mistaken VB code snippet, it is already fixed.
The current software that we use does not support adding scroll bars to each code snippet box. However, if more people are requesting the same feature, we will consider the possibilities of adding such.
The copy code functionality does not work in Chrome and FireFox out of the box, since those browsers does not support Clipboard editing. Internet Explorer does support access to Clipboard out of the box.
I hope that you find this information helpful.
Your Telerik points have been updated for reporting the documentation issue.
