The “Back” and “Forward” buttons are commonly found in web browsers and are essential navigation tools that allow users to move backward or forward through their browsing history within a particular browsing session.
Key points about Back and Forward buttons:
- Back Button: The “Back” button in a web browser enables users to navigate backward through the web pages they have previously visited in the current browsing session. Each time a user clicks the “Back” button, they are taken to the previous page in their browsing history. This feature is helpful for retracing steps, revisiting previously viewed pages, or returning to the previous location within a website.
- Forward Button: The “Forward” button, usually located adjacent to the “Back” button in a web browser, allows users to navigate forward through the web pages they previously accessed if they have navigated backward using the “Back” button. Clicking the “Forward” button takes users to the next page in their browsing history, moving them forward through the previously visited pages.
- Browsing History: Both the “Back” and “Forward” buttons rely on the browsing history maintained by the web browser. The browsing history records the URLs or web addresses of pages visited during the browsing session, enabling users to revisit these pages using the navigation buttons.
- Keyboard Shortcuts: In addition to the graphical buttons in the browser’s interface, users can navigate backward and forward using keyboard shortcuts. For example, pressing Alt + ← (left arrow key) typically functions as the “Back” button, while Alt + → (right arrow key) acts as the “Forward” button in many browsers.
- Session-based Navigation: The Back and Forward buttons facilitate navigation within the current browsing session. Once a session ends (by closing the browser or starting a new session), the browsing history for that session is typically cleared, and the Back and Forward navigation relates only to the current session’s history.
