@ronald, sometimes using the Found Image Action is the only way to find and click on a specific element on a window. But I try to use it as a last resort, because it is usually NOT as reliable as using other techniques that specifically address the desired element (button, link, etc).
XPath is one great tool for finding elements on a web page. Having found the element, then you can do stuff with it, like, click on it, copy it, etc. For a list of topics about XPath, see Topics tagged with 'xpath'
However, XPath is NOT easy to use for those unfamiliar with it. It will take some study to learn/master it. I'm still learning myself. But, for those that do understand it well, like @ComplexPoint, it becomes a tool easy to use.
