Wrapping

An interface navigation technique where the focus or cursor automatically returns to the beginning of a line, list, or group of elements when it reaches the end, or vice versa. In accessible interfaces designed for low bandwidth input, wrapping reduces the number of signals needed to reach any target by allowing users to approach items from either direction. For example, if the cursor is near the end of a row of links, wrapping means the user can continue forward to reach the first link rather than reversing direction, which is particularly important when producing a "reverse" signal is error-prone or costly.
