Navigation means how fast you switch between the pieces of code you are working on. The faster you switch the more productive you are. Here is a list of notable features which make your navigation experience smooth.
Most of the time you work with a final set of files. It means you have to switch between them quickly all the time. The real time-saver here is action called Recent files via Ctrl+E. By default the focus is on the last accessed file. In the meanwhile you can open any tool window through this action.
Another useful feature similar to Recent files is Recently edited files, available via Ctrl+Shift+E. This is the easiest way to get back to the code you are working on.
Refer to the section Navigating to Recent for details.
When you are not switching between files you probably navigate within a file. The shortest way to do it is to press Ctrl+F12. The popup shows you the structure of file and allows you quickly navigate to any item. Just as always you don’t need to touch mouse.
Note that the speed search works here as well. The second press of the shortcut displays inherited members.
Just like the task switcher in an operating system, IntelliJ IDEA provides a switcher between opened files and tool windows. This action is available via Ctrl+Tab.
Another useful feature worth to mention is Jump to navigation bar via Alt+Home. The navigation bar in the top of the window is useless most of the time. That’s why developers usually hide it and call on demand via a shortcut.
The navigation bar supports the speed search and other actions, such as code generations, documentation popup, etc.
Refer to the section Navigation Bar.
Navigation between methods
If you need to jump over the methods quickly, just pressAlt+UpAlt+Down.
A similar action for navigating between braces is available via Ctrl+Open Bracket or Ctrl+Close Bracket.
Navigation to anything
The next feature which is practically one of the most used in IntelliJ IDEA, is Navigate to Class, File and Symbol.
This feature is available via Ctrl+N supports sophisticated expressions, including camel humps, path, line navigate to, middle name matching and many more. If you call it twice, it shows the results out of the project classes.
Just like for classes, it works for files as well, via Ctrl+Shift+N . The results are sorted by relevance to the expression.
And finally, the most tricky feature is to navigate to a symbol via Ctrl+Shift+Alt+N. The IDE constantly maintains the index of all symbols in project (and within libraries as well) for quick resolve and navigation. So you can type an expression and find a method or a field you need in a second.
If you need to open the file in a particular tool window (or Finder/Explorer), you can do it via Select In action by pressing Alt+F1.
Refer to the section Navigating Between IDE Components for details.
