Bring back context-sensitive help in ArcGIS for Desktop

[SteveMiller1]

I understand that ESRI's context-sensitive help was based on the obsolete MS WinHelp format, but please bring it back in the same detail, with current technology.  As always, the very best documentation is where you need it, when you need it.
