What action is performed by hitting the tab key in a web form?

Pressing the tab key in a web form is commonly used to navigate between different input fields or interactive elements within that form. Essentially, the tab key moves the focus from one element to the next. This allows users to fill out forms more efficiently without having to use a mouse or trackpad, making it an essential part of accessibility and usability.

When you're filling out forms, hitting the tab key directs the cursor to the next form field, such as moving from a text box to a radio button or to the next text box. This sequential navigation is particularly useful for users who rely on keyboard input, enhancing the overall user experience.

While submitting the form, resetting inputs, or opening help text are actions that may be performed in a web form, these actions correspond to different keys or events, not the simple act of hitting the tab key.
