JetBrains PyCharm apparently uses the JavaHelp help viewer in its PyCharm product (and possibly in other JetBrains IDEs too).

I created a couple of issues in their bug tracker:

• http://youtrack.jetbrains.com/issue/IDEABKL-6629 : Wanted: Keyboard shortcuts in help viewer
• http://youtrack.jetbrains.com/issue/IDEABKL-6630 : Wanted: "Search in page" in help viewer

I'm guessing this is pretty easy to implement (at least the first one). Pointers to where (in the source code)/how to implement this would be helpful.
