# Edit in Multiple Tabs in the Text Editor

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

You can have multiple files open simultaneously in API Designer’s text editor. Each file can be open
in its own tab.

## Opening Files in New Tabs

There are four ways that you can open a file in a new tab:

- Open the context menu for a file in the file tree by clicking the three dots to its right, and
  then select **Open in new tab**.

- Press the Command key (MacOS) or the Control key (Windows) and click the name of the file in the
  file tree. +\[NOTE\]

Clicking a filename in the file tree without first pressing either of these keys replaces the file
that is open in the current tab.

- Place your cursor in the name of a file in a file reference such as an `include` tag in RAML or a
  `$ref` keyword in OAS.

  Then, press the Command key (MacOS) or the Control key (Windows) and click the filename.

- Click a filename in the **Location** column in the errors view at the bottom of the screen.

## Navigating to Different Tabs

The tab bar appears at the top of the editor only when at least two files are open.

To switch to the tab to the left of the one currently open, follow either of these steps: \* Press
Option + Shift + Tab (MacOS) or Alt + Shift + Tab (Windows). \* Open the menu on the tab bar by
clicking the ellipsis and select **Previous Tab**.

To switch to the tab to the right of the one currently open, follow either of these steps: \* Press
Option + Tab (MacOS) or Alt + Tab (Windows). \* Open the menu on the tab bar by clicking the
ellipsis and select **Next Tab**.

## Closing Tabs

To close a single tab, click the X icon that appears on it.

To close all tabs but the currently open one, click the ellipsis on the right side of the tab bar
and select **Close All Other Tabs**.
