Editor Swap is a Blender add-on from carlosmu that lets you switch between editors using either a button on the editor's header or a keyboard shortcut. The linking between editors is fully customizable, so you can swap sequentially between two or more editors.
The default shortcut is CTRL + ALT + X, and you can reassign it to a combination of your choice from the add-on preferences. The same preferences let you change icons and behaviour, and you can hide the header button entirely if you'd rather use the shortcut alone.
Installation follows the standard Blender add-on process: download the zip and add it from Edit > Preferences > Add-ons. From Blender 4.2 onward, you can also drag the zip file directly into the interface. Editor Swap is compatible with Blender 3.6 through 4.4 and is distributed under the GPL license.
