Viewing External Documentation
External documentation makes it possible to get additional information for the symbols at caret. In contrast to the quick documentation, this feature shows the documentation in an external browser, which helps study the symbol in more detail, navigate to related symbols, and retain the information for further reference.
PyCharm shows documentation for SciPy, NumPy, PyGTK, and the other modules you've installed for your Python interpreter. External documentation should be properly configured in the Python External Documentation page of the Settings/Preferences.
To view documentation for a symbol at caret in an external browser, do one of the following:
On the main menu, choose.
While in the Quick Documentation Lookup window, click the link at the bottom of the window.
