To open the IDE Help:
If the online help is not available when you open an IDE dialog, from the main menu, select General, select Web Browser, and then select Use external Web browser. Setting this option causes online help to be displayed in an external browser.
, expandOn some Linux systems, an external browser isn't specified in the preferences by default, and therefore it must be created manually by clicking New, specifying a name, and then clicking Browse to locate the external Web browser.
If you're using an external web browser, the IDE starts a web server running on a random port (alternatively, you can specify a port in the Preferences window using
). You can access the help system through this port using any web browser; you aren't limited to the browser launched by the IDE.Unless you're extremely low on RAM, keep the online help system open until you're finished using the IDE. This prevents any anti-spyware programs from confusing the IDE with a virus, and also lets you refer to the online documentation quickly whenever you need to.
