JetBrains Rider 2022.1 Help

Editor tabs

Every time you open a file in the editor, a dedicated tab is added to the editor frame, with a label displaying the filename.

Manage editor tabs

  • Use commands in Window | Editor Tabs menu.

  • Configure preferences for editor tabs on the Editor | General | Editor Tabs page of the IDE settings Ctrl+Alt+S.

  • Right-click a tab and use its context menu.

  • Click a tab label with the middle mouse button or click Close on the tab label to close the tab.

  • Alt-click Close on the tab label to close all other tabs except the pinned ones.

  • Use keyboard shortcuts: Ctrl+F4 to close the active tab, Alt+Right/Alt+Left to switch to the next or previous tab.

Open files in the preview tab

The preview tab allows you to view files in a single tab one by one without opening each file in a new tab. This is helpful if you need to look through several files without exceeding the tab limit.

  1. In the Solution explorer Alt+1, click the Show Options Menu button and select the Enable Preview Tab option.

    You can also enable the preview tab in Settings/Preferences | General | Editor Tabs | Opening Policy.

  2. In the Solution explorer, select a file that is not already open in any other tab.

    The name of the file is written in italic to indicate the preview mode. Any other file that you select will replace the previous one in the preview tab.

    Start editing the file to exit the preview mode and change it to a regular tab.

    Note that when the preview tab is enabled, the Open Files with Single Click option is ignored. Double-click a file to open it in a regular tab.

Change the maximum number of open files

JetBrains Rider limits the number of files that you can simultaneously open in the editor. When the number of open files reaches the limit, the editor closes the less recent tabs (unless they are pinned) according to the tab closing policy, which is defined in the Editor | General | Editor Tabs page of the IDE settings Ctrl+Alt+S By default, the maximum number of open files is limited to 10, but you can change it if necessary.

  1. Press Ctrl+Alt+S to open the IDE settings and select Editor | General | Editor Tabs.

  2. Enter the desired maximum number of open editor tabs in the Tab limit field and apply the changes.

  3. By default, the maximum number of open tabs that you can allow is limited to 100. If you want to increase that limit, press Ctrl+Shift+A or choose Help | Find Action from the main menu. In the popup that opens, start typing Registry, select the corresponding item and press Enter. In the Registry dialog, search for the ide.max.editor.tabs key and change its value.

Change position of tab labels or disable tabs altogether

By default, the tab labels appear at the top of the editor, but you can change their placement as required, and have tab labels at the bottom, left, or right sides of the editor. You can also disable editor tab altogether so that the entire editor frame is dedicated to a single document, and each new document you open replaces the previous one. Note that the tab label placement is a global setting that applies to all solutions.

  1. Press Ctrl+Alt+S to open the IDE settings and select Editor | General | Editor Tabs.

  2. Use the Placement selector to choose the desired position of tab headers.

    To disable editor tabs altogether, select None from the Placement selector.

You can jump from one tab to another as your editing session requires. While you move between the editor tabs, JetBrains Rider remembers the caret position within each opened file.

Navigate open editor tabs

  • Right-click the current editor tab and choose Select Next/Previous Tab from the context menu.

  • Press Alt+Right or Alt+Left to move the focus to the editor tab located next to the right or to the left from the active editor tab.

  • Press Ctrl+Tab to use the Switcher. While holding down Ctrl, you can use Tab or Shift+Tab to pick the desired editor tab in the right-hand part of the popup:

    JetBrains Rider: Switcher popup

Go back and forth through the history of visited tabs

  • Press Ctrl+Alt+Left or Ctrl+Alt+Right, choose Navigate | Back / Forward from the main menu, or click App actions back or App actions forward on the toolbar.

    Note, that these commands also take into account your movements within the document, so if you worked in several places of the same file, these commands will navigate you through those places before moving to the next or previous tab.

  • Press Ctrl+E or Ctrl+Shift+Comma to navigate to the recently veiwed or edited files.

  • On a macOS computer, you can use the three-finger right-to-left and left-to-right swipe gestures.

If too many tabs are opened and shown in a single row, the less recent tabs are hidden.

View hidden editor tabs and select the active editor

  1. Do one of the following:

    • Choose Window | Editor Tabs | Show Hidden Tabs from the main menu.

    • Click App general more tabs in the upper right corner of the editor area.

  2. Click the name of the desired document:

    View all tabs

The command Show All Tabs and the icon App general more tabs are only available when:

  • The Show tabs in single row checkbox is selected on the Editor | General | Editor Tabs page of the IDE settings Ctrl+Alt+S.

  • Some of the opened tabs are not visible because they do not fit in the editor window.

Pin and unpin tabs

When the specified tab limit is reached, JetBrains Rider will close old tabs when you open new documents. To prevent a tab from being closed automatically, you can pin this tab.

To pin or unpin a tab, right-click it and choose Pin Tab or Unpin Tab from the context menu.

When a tab is pinned, it is moved to the left within its tab group and there is a special marker on it, which you can click to unpin the tab.

Unpin tab

You can also pin and unpin tabs by dragging and dropping them over other pinned or unpinned tabs.

If you tend to open a lot of tabs, you can keep all your pinned tabs in one row. To do so, select Show pinned tabs in a separate row on the Editor | General | Editor Tabs page of the IDE settings Ctrl+Alt+S.

When some tabs are pinned, you can leave only them and close all unpinned tabs — right-click any editor tab and choose Close All but Pinned from the context menu.

Split editor into multiple tab groups or windows

You can split the editor window into as many tab groups as required. For example, you can open a file in the right split, so that the currently opened document also stays visible.

When there are several editor tabs, the easiest way to add a new tab group or move files between tab groups is to drag a tab to the desired side of the editor frame.

Splitting editor window with drag-and-drop

When there are multiple tab groups, you can choose Window | Editor Tabs | Goto Next/Previous Splitter from the menu to jump between them.

Open a file in a new tab group

  • Choose any file in the Solution Explorer and press Shift+Enter or right-click it and choose Edit | Edit 'file' in Right Split.

  • If there are several editor tabs, right-click a tab and choose Split and Move Right or Split and Move Down.

You can also split a single file into several tabs in different tab groups. This way you will be able to scroll through a part of a file having another part of the file in view in another group.

Split a single file into multiple tabs

  • Right-click a tab and choose Split Right or Split Down.

  • Choose Window | Editor Tabs | Split Right/Split Down from the main menu.

When you remove tab groups, all files from the removed group are moved to the next group to the left or above it. If there are any files split between multiple groups, the split parts from the removed group are closed.

Remove tab groups

  • To remove a tab group containing a single tab, drag this tab to another group.

  • To remove a tab group, right-click any tab in this group and choose Unsplit.

  • To remove all tab groups, right-click any tab in any group and choose Unsplit All.

Manage tab groups

  • To change the layout of tab groups, right-click a tab and choose Change Splitter Orientation.

  • To slightly extend or shrink the tab group with the active file, choose Window | Editor Tabs | Stretch Editor to Top/Left/Bottom/Right from the main menu.

  • To extend a tab group with the active file to the maximum and shrink all other groups to the minimum width/height, choose Window | Editor Tabs | Maximize Editor from the main menu.

  • To allocate the same width and height for each tab group, choose Window | Editor Tabs | Normalize Splits from the main menu.

Editor tabs and tab groups can be displayed in separate windows, detached from the main IDE window. The detached windows will be managed by your operating system and may be helpful if you are using several monitors. Each detached window can work as a tab group, or you can arrange multiple tab groups within each window.

Open editor tabs in separate windows

  • To open an editor tab in a new detached window, set the caret in a tab that you want to detach or select a file in any tool window, and then press Shift+F4.

    If you started from an editor tab, the file will be split and displayed in both the original window and the new detached window.

  • To move an editor tab to a new or existing IDE window, drag it and release the mouse when the tab is outside any IDE windows or over another IDE window.

Arrange tabs in the alphabetical order

To have editor tabs always arranged in the alphabetical order, select Sort tabs alphabetically on the Editor | General | Editor Tabs page of the IDE settings Ctrl+Alt+S.

When this option is enabled, you will not be able to drag and drop tabs within the same tab group.
