Not able to select 'SAVE AS" from IE frame

you should get a selector for the dropdown arrow.
click on that.
to get a selector for the “Save As” - open uiExplorer > select target element > press F2[this will give 3 seconds to select another element. During this time you can click the drop down and the sub menu will be visible] > click “Save As” option after the 3 second window is elapsed.

Now that you have selectors for dropdown and the “Save As” menu item you should be able to use the click activity as usual.
