The manual input control in pagination allows users to enter a specific page number they wish to navigate to directly. This feature is particularly useful in long documents or lists with numerous pages, where scrolling through each page or using standard navigation controls (like "Next" or "Previous") can be time-consuming.

To use it, a small input field is provided, typically located near the pagination controls. Users can type in the page number they desire and hit enter or click a go button, which then takes them straight to that page.

When designing this control, make it easily identifiable and simple to use. The input field should be prominent enough to be noticed, but not so large that it disrupts the overall design.
