t's only possible in c# action
first you find the proper element:
use any usefule method of instance.ActiveTab.FindElemtBy...
than you have to be sure the element is placed in the visual area or make the element.ScrollIntoView()
get the element position relative to vusual area of tab (actualy the left upper corner of element)
int left = element.DisplacementInTabWindow.X;
int top = element.DisplacementInTabWindow.Y;
use any offset
ltop -= 10;
there are only two standart methods to make the click action like
instance.ActiveTab.MouseClick(left, top, "left", "click");
or
instance.Click(left1, left, top, top, "Left", "Normal");
