In keyboard navigation, how can users switch between tabs?

The Tab key is the standard method for keyboard navigation that allows users to switch between interactive elements such as tabs, links, and form fields on a web page. When a user presses the Tab key, the focus moves to the next focusable element in the order they appear in the document. This functionality is crucial for users who may not utilize a mouse due to various disabilities or accessibility needs, as it facilitates seamless navigation through the content of a page.

In contrast, the Spacebar is typically used to activate or select an option that is currently focused, rather than transitioning between elements. The Enter key serves a similar purpose, activating the focused item rather than moving the focus itself. The Shift key, when used in conjunction with the Tab key, allows users to move focus backward through the elements. While the Shift key is important in keyboard navigation, it does not independently serve as a means to switch between tabs. Hence, the Tab key is recognized as the primary tool for this navigation.
