"The Up One Level Button" is a Chrome extension developed by heppokofrontend under a free license. It falls under the Browsers category, specifically in Add-ons & Tools. This extension simplifies navigation by allowing users to move from the current web page to its parent directory.

The extension offers two convenient methods for navigation. Users can either click the icon from the list of Google Chrome extensions or use the shortcut key combination Alt+↑ or Cmd+↑. The shortcut key functionality can be toggled on and off from the context menu, with the default setting being disabled. However, it's important to note that the extension may not work on some Google pages and pages opened before its installation, requiring a page reload for proper functionality.
