In the context of UiPath selectors, what is an anchor?

In UiPath, an anchor is used in conjunction with selectors to improve the accuracy of identifying UI elements within an application. When a selector is not reliable due to dynamic content or changing layouts, an anchor—a stable element nearby the target—can be used to pinpoint the target element with greater precision. The anchor serves as a point of reference, and the relative position of the target element to this anchor is used to identify it during automation tasks1.
