IntelliJ IDEA 2021.3 Help

Tool windows

Tool windows provide access to development tasks: viewing your project structure, running and debugging your application, integration with version control systems and other external tools, code analysis, search, navigation, and so on. By default, tool windows are attached to the bottom and sides of the main window. However, you can rearrange and even detach them to use as separate windows, for example, on another monitor.

The following screenshot shows several common tool windows occupying space around the editor:

Tool windows
  1. Project tool window

  2. Structure tool window

  3. Run tool window

  4. Maven tool window

Some tool windows are always available (for example, Project and Structure) , some are activated when a specific plugin is enabled or your project has a specific structure (for example, Maven, Gradle, and Spring), and some appear only when you perform a certain action (for example, Run, Debug, and Find).

For example, the Run tool window appears only after you run your code. It is accessible from the main menu View | Tool Windows | Run or using the shortcut Alt+4 as long as there is some output in the console and you don't close all the tabs in it.

Open a tool window

To show or hide a tool window, do one of the following:

  • From the main menu, select a tool window under View | Tool Windows.

  • Use the corresponding shortcut, for example, Alt+1 to open the Project tool window. If there is no shortcut for a tool window, you can assign it as described in Configure keyboard shortcuts.

  • Click the corresponding tool window button on the tool window bar.

  • Select Window | Active Tool Window | Hide All Windows/Restore Windows from the main menu.

  • To change focus from a tool window to the last caret location in the editor, press Escape.

  • If you selected a code item in a tool window, for example, a search result, a code issue, or a bookmark, press F4 to open the corresponding file and locate this item in the editor.

  • To change focus from the editor back to the last active tool window, press F12 or select Window | Active Tool Window | Jump to Last Tool Window from the main menu.

Tool window bars and buttons

Tool window bars on the edges of the main window contain buttons to show and hide tool windows. Right-click a tool window button to open its context menu, where you can change the viewing mode and move the tool window. You can also drag tool window buttons to rearrange tool windows on the bars.

Tool window components

Generally, all tool windows have a title bar, a toolbar, and a content pane.

Components of a tool window

Some tool windows are also separated using tabs or a dropdown selector in the title bar, based on the functionality that it covers. Select Window | Active Tool Window | Group Tabs to show tabs. Disable this option to show a dropdown menu.

The title bar contains the tool window options menu The tool window options menu for changing the viewing mode and the position of the tool window. You can also access these options by right-clicking the title bar or the tool window button. Some tool windows can have other options in this menu, depending on the functionality (for example, to sort, filter, and group items listed in a tool window).

Click the Hide button to hide the tool window and use other buttons that may be on the title bar, for example:

  • The Expand All button and The Collapse All button to expand and collapse the contents of the tool window

  • The Select Opened File button to locate and select the file from the editor in the tool window

Actions from the tool window toolbar are usually also available in the main menu and context menus. Some of them can also be executed with a default shortcut. You can assign shortcuts for actions as described in Configure keyboard shortcuts.

For all tool windows that display tree-like structures (for example, Project tool window) you can display vertical lines that mark indent levels in tree views and help you better understand the hierarchy of the components in your project. To display these lines, enable Show tree indent guides on the Appearance and Behavior | Appearance page of the IDE settings Ctrl+Alt+S.
