These options take advantage of shortcuts in the view toolbar and Measure Items window. They are recommended because they bundle multiple features into one spot to aid in your data editing tasks.
Options for adding measure items exist in the grid or view explorer, which are available when you right-click in either spot and use the Add option off of the pop-up menus that display.
