Figure 4: This figure shows a T-pattern of length 4 (m = 4). Here a repeated m = 2 pattern comes first (x,b, automanipulate x, e, automanipulate) meaning x begins and ends fiddling with something without paying attention to it and this is followed by another m = 2 pattern (y, e, view, long y, b, lookat, picturecard ) meaning that x begins ordering y to give up the viewer and then y stops manipulating the viewer. The green color indicates that both pattern 107 and the last event-type (terminal 4) are markers (see about T-markers below). The four vertical green lines indicate all four times the viewer passes from child y to child x.
