JetBrains Rider 2019.3 Help

Editor Tabs

Every time you open a file for editing, a dedicated tab is added to the editor window, next to the active editor tab.

JetBrains Rider can limit the number of tabs opened in the editor simultaneously. When the number of tabs reaches its limit, the editor closes the tabs according to the tab closing policy, that is defined in the Editor | General | Editor Tabs page of JetBrains Rider settings Ctrl+Alt+S By default, the tab limit is 10, but you can change it if necessary.

To manage editor tabs:

  • Use commands in Window | Editor Tabs menu.

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

  • Click Close on the tab label to close the tab or Alt-click it to close all other tabs.

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

Configure the behavior of editor tabs

  1. In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | General | Editor Tabs.

  2. Change the maximum allowed number of tabs: type the desired maximum allowed number of the editor tabs to be opened at a time in the Tab limit field.
    If the tab limit equals 1, the tabs will be disabled. If you want the editor to never close the tabs, type some unreachable number.
    With the disabled tabs, use the View | Recent files Ctrl+, command to quickly switch between files.

  3. By default, the tab headers appear on top of the editor, but you can change their location as required, and have the headers at the bottom, left, or right sides of the editor. Note that the tab header placement is a global setting that applies to all projects.
    Use the Placement selector to choose the desired position of tab headers.
    To disable editor tabs altogether, select None from the Placement selector.

To navigate between editor tabs

This approach allows jumping 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.

  • 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

This approach enables you to move back and forth through the history of your navigation, same way as it is done in a Web browser. As you move from file to file during your editing session, JetBrains Rider keeps track of the visited locations and enables you to go back, using the Navigate | Back / Forward commands.

  • On the main toolbar, click icons actions back or icons actions forward.

  • Choose Navigate | Back / Forward from the main menu.

  • Press Ctrl+Minus or Ctrl+Shift+Minus.

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

View all editor tabs and select the active editor

If all opened tabs are shown in a single row, some of the tabs may become invisible. JetBrains Rider helps display the list of the opened editor tabs that did not fit in the editor window and have become invisible whereupon you can choose the tab to activate.

  1. Do one of the following:

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

    • Click icons general moreTabs

    The list of all the tabs that are opened but invisible appears. The names of the tabs, which are currently visible, are displayed on the light background; the names of the tabs outside of the main window are shown on the darker background.

  2. Click the name of the desired editor tab:
    view all tabs

    The selected editor tab becomes active and gets the focus.

The command Show All Tabs and the icon icons general moreTabs are only available when:

  • The Show tabs in single row checkbox is selected in the Editor | General | Editor Tabs page of JetBrains Rider 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. Besides, when you close the editor tabs, you have an option to leave pinned tabs opened and close only the unpinned tabs.

When a tab is pinned, there is a special marker on it:

pin1

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

Split and unsplit editor window

Splitting the editor window divides it into independent panes. You can split the editor window into as many panes as required, each one containing multiple tabs.

Each pane can be allocated vertically or horizontally. Thus, splitting helps create different editor layouts and organize tabs into groups. For example, you can scroll through a part of a file, having at the same time the possibility to view the lines in its other part.

Split and unsplit the editor window

  1. Switch to the desired editor tab and right-click it.

  2. To split an editor tab and create another tab for the document, choose Split Vertically or Split Horizontally from the context menu.

  3. To create a new tab group and move an editor tab to this group without creating another tab for the document, choose Split and Move Right or Split and Move Down from the context menu.

  4. To change the splitter orientation, choose Change Splitter Orientation from the context menu.

  5. To remove the splitter, choose one of the following commands from the context menu:

    • To remove splitting in the active tab, choose Unsplit.

    • To remove splitting in all the open editor tabs, choose Unsplit All.

Detach editor tabs

You can detach editor tabs, and move them to separate frames. The detached editor tabs can be split or unsplit, and you can move editor tabs between split panes.

To detach an editor tab, do one of the following:

  • Drag this tab outside of the main window. You can also use Alt+mouse. A preview thumbnail appears:

    rdr detach editor tab

  • Press Shift+F4.

    rdr detach editor tab frame

The content of the editor tab opens in a separate frame.

To attach an editor tab, drag it from its frame and drop to the main JetBrains Rider frame until the tab name appears:

rdr attach editor tab

Arrange tabs in the alphabetical order

The alphabetical sorting of the editor tabs is available regardless of the tabs position. However, alphabetical order for top and bottom placement becomes available, when the Show tabs in single row check command is selected on the Window | Editor Tabs | Tabs Placement menu.

Sort editor tabs alphabetically

  1. Right-click an editor tab.

  2. Select Sort Tabs by Filename.

    If this check command is selected, the tabs headers are presented in alphabetical order. Otherwise, the editor tab headers appear in the opening order of the corresponding files.
