The project tool window is just one of a number of tool windows available within the Android Studio environment.

== The Tool Windows ==

* '''Project''' – The project view provides an overview of the file structure that makes up the project allowing for quick navigation between files. Generally, double clicking on a file in the project view will cause that file to be loaded into the appropriate editing tool.

* '''Structure''' – The structure tool provides a high level view of the structure of the source file currently displayed in the editor. This information includes a list of items such as classes, methods and variables in the file. Selecting an item from the structure list will take you to that location in the source file in the editor window.

* '''Captures''' – The captures tool window provides access to performance data files that have been generated by the monitoring tools contained within the Android Monitor tool window.

Once displayed, the switcher will remain visible for as long as the Ctrl key remains depressed. Repeatedly tapping the Tab key while holding down the Ctrl key will cycle through the various selection options, while releasing the Ctrl key causes the currently highlighted item to be selected and displayed within the main window.

In addition to the switcher, navigation to recently opened files is provided by the Recent Files panel (Figure 4 8). This can be accessed using the Ctrl-E keyboard shortcut (Cmd-E on Mac OS X). Once displayed, either the mouse pointer can be used to select an option or, alternatively, the keyboard arrow keys can be used to scroll through the file name and tool window options. Pressing the Enter key will select the currently highlighted item.
