Which key is used to navigate to the next field in the documentation platform?

The Tab key is used to navigate to the next field in many documentation platforms, and this functionality is a standard feature in most software applications. When using a form or an input field, pressing the Tab key causes the cursor to move to the next available input area, allowing for efficient data entry without needing to use the mouse. This feature enhances user experience by enabling a quicker and smoother workflow for tasks such as filling out forms or navigating through options.

In contrast, the other keys have different functions. The Enter key typically submits a form or a command rather than moving to the next field. The Spacebar often activates a selected item rather than facilitating navigation between fields. The Shift key is primarily used in combination with other keys, such as creating capital letters or highlighting text, rather than serving as a navigation tool on its own. Thus, the Tab key stands out as the correct choice for moving to the next field in a documentation platform.
