Navigate current context

With JetBrains Rider, you can navigate the structure of the current document using the Structure window, which greatly simplifies navigation in large files. The window is synchronized with the editor: as you switch to another editor tab, the window displays the structure of the corresponding file.

tip

To list file members using a popup instead of a tool window, press Alt0\

Right from the Structure window, you can access even more actions. To check available commands, you can right-click any symbol.

• To open a specific type or member in the editor, double-click it or press Enter or F4.

• Navigate from symbols

• Find usages of symbols ShiftF12

• Generate type members AltInsert

• Perform refactorings ( CtrlShift0R)

• If the opened file contains unit tests, these are marked with corresponding icons displaying the status of their last execution. You can also run and debug unit tests right from inside the Structure window.

tip

To search items in the Structure window, just start typing a name or a CamelHumps abbreviation.

Editor breadcrumbs help you quickly understand where your caret is with regard to the structure of the current document as well as navigate that structure. With editor breadcrumbs enabled, you will always see the path from the root code element to the current caret position right in the editor.

The first element in a C#/VB.NET file includes the project name where the file is included and the framework that is used for the design time inspection in the project. If the project targets multiple frameworks, you can click the first element and change the framework; if the file is included in several projects, you can click and change the project in whose context the file is analyzed.

To jump to a parent element in the source code, click the breadcrumb with its name. If you click the namespace element in a C#/VB.NET file, you will be able to navigate to all the files where this namespace is used.

By default breadcrumbs are shown at the bottom of the editor. To display them at the top or hide them altogether, right-click the breadcrumb bar and choose Breadcrumbs | Top or Breadcrumbs | Don't show.

You can also do that as well as configure in which languages and with which colors editor breadcrumbs should be displayed on the Editor | General | Breadcrumbs page of the IDE settings  CtrlAlt0S.

You can hover over the scrollbar to view source code above or below the currently visible area:

You can disable this behavior by clearing the Show code lens on scrollbar hover checkbox on the Editor | General | Appearance page of JetBrains Rider settings CtrlAlt0S.

note

The term code lens used for this feature in the settings is not related to Visual Studio's CodeLens functionality, which is called Code Vision in JetBrains Rider.

With a single shortcut, you can jump in the editor to the declaration of a type or a function from any position within its body.

tip

JetBrains Rider provides a related feature — Select Containing Declaration ( AltShift0]) , and you can also use AltShift0[/ to jump to the opening/closing brace of the enclosing code block .

With the Next/Previous Member commands, you can quickly navigate between members and nested types in code files or between tags in markup files.

You can switch between files opened in the editor, split editor tabs, and tool windows (docked or floating) similarly to your OS application switcher. The switcher brings up a popup consisting of two columns: the left one displays tool windows, the right one shows editor tabs. If no files are currently opened, or there is just one tab, the switcher shows recently opened files:

When you select a file, type, member, or other code item in the editor or one of the tool windows, you can quickly locate it in another IDE component.

tip

You can also double-click selected file or member in one of the tool windows or press Enter to open it in the editor.

This handy navigation feature lets you expand the tree in the Solution Explorer, auto-scroll and highlight the item corresponding to the current document. It is especially useful when you have a massive solution, or a limited screen area that forces you to shrink the Solution Explorer window to the limit.

note

Note that this command will not work if the file that is opened in the editor is not included in the current solution.

tip

You can also locate a library symbol in the Assembly Explorer right from the source code where this symbol is used: While your caret is on the symbol, press Alt0` or choose Navigate | Navigate To… from the main menu , and then select Locate in Assembly explorer.

The Go to Line command lets you quickly jump to any line of code in the current document.

To go to a specific line in any other file, use the Go To File command (CtrlShift0T), type : (colon) after the target file name, and specify the line number after that.

tip

To display line numbers in the editor, select Show line numbers on the Editor | General | Appearance page of JetBrains Rider settings CtrlAlt0S.
