If Pixel Exists

Causes the steps following this action to execute if the specified pixel(s) is(are) in the specified state. If not, execution follows the next Else or End If action, whichever comes first. Commonly used to check if a graphic or area of the screen matches (or stops matching) a "checksum" of pixel colors. Very useful for detecting subtle changes in a window's contents that cannot be measure by any other means. In visual mode, it is easy to create the checksum values, while in the properties of the action, move the mouse pointer around the target window while repeatedly pressing the INSERT key.
