Quick Switcher is a tool designed to enhance navigation efficiency within ReadMe by allowing users to quickly search and access various elements such as pages, settings, and projects with a simple keyboard shortcut—⌘ + K on Macs or Ctrl + K on Windows. This functionality aims to alleviate the hassle of locating specific pages, settings, or projects by providing a fast and streamlined way to jump directly to the desired destination. Additionally, the Quick Switcher can be accessed via a magnifying glass icon at the bottom of the sidebar, and users are encouraged to provide feedback on potential improvements through feature requests.
