Tool windows

Show/hide: View | Tool Windows

Tool windows provide functionality that supplements editing code. For example, the Project tool window shows you the structure of your project, and the Run tool window displays the output of your application when you run it.

By default, tool windows are docked to the sides and bottom of the main window. You can arrange them as necessary, undock, resize, hide, and so on. Right-click the title of the tool window or click The Show Options Menu button in the title for its arrangement options.

You can assign shortcuts to quickly access the tool windows that you frequently use. Some of them have shortcuts by default. For example, to open the Project tool window, press Alt01, and to open the Terminal tool window, press AltF12. To jump from the editor to the last active tool window, press F12.

Context menus

You can right-click various elements of the interface to see the actions available in the current context. For example, right-click a file in the Project tool window for actions related to that file, or right-click in the editor to see actions that apply to the current code fragment.

Most of these actions can also be performed from the main menu at the top of the screen or the main window. Actions with shortcuts show the shortcut next to the action name.

Popup menus provide quick access for actions related to the current context. Here are some useful popup menus and their shortcuts:

  • AltInsert opens the Generate popup for generating boilerplate code based on the context.

  • CtrlAltShift0T opens the Refactor This popup with a list of contextually available refactorings.

  • AltInsert in the Project tool window opens the New popup for adding new files and directories to your project.

  • Alt0` opens the VCS Operations popup with contextually available actions for your version control system.

You can create custom popup menus using quick lists of actions that you often use.

Main window

The main window lets you work with a single CLion project. You can open multiple projects in multiple windows . By default, the window header displays the name of the project and the name of the currently open file. If there are multiple modules, it will also show the name of the relevant module.

To show the full path to the project and to the current file, select Always show full paths in window header on the Appearance & Behavior | Appearance page of the IDE settings CtrlAlt0S.
