What is f4 on mac?

F4 on macOS is a function key that serves multiple purposes depending on the context in which it is used.

1. Launchpad: When you press F4 on macOS, it will open Launchpad, which is a way to quickly access and organize your applications. This can be useful for users who prefer a visual way of launching applications rather than using the Dock or Spotlight search.

2. Mission Control: If you press F4 while holding down the fn key, it will open Mission Control. This feature provides an overview of all your open applications, desktops, and spaces, making it easier to navigate and switch between them.

3. Expose: In older versions of macOS, pressing F4 would activate Expose, which allowed users to quickly view all open windows arranged neatly on the screen for easy switching. This feature has been merged with Mission Control in more recent versions of macOS.

Overall, F4 on macOS provides convenient shortcuts for managing and navigating your applications and windows, helping improve productivity and efficiency.
