You could hack the code of your favourite IDE (e.g. add a macro, modify the source) to google whatever is currently selected (e.g. WriteLn) by you with an additional qualifier

  site:stackoverflow.com

for instance

  WriteLn site:stackoverflow.com

So it would open up the top result of Google's SERP, i.e.

https://stackoverflow.com/questions/617654/how-does-writeln-...

There key difference with this approach is that in TP you had a very good help page, and here you get only the top result. Big difference!

And pray that that the answers on Stackoverflow are relevant.

I like using zeal-at-point in emacs, it is quite useful. https://github.com/jinzhu/zeal-at-point
