its location to select one element or click left mouse button and move
it over the desired elements to select multi-elements.

If SELECT BY is toggled ON, there are three ways to select an element. The user may select by part, type, or range. See Figures 4.3.4 ~ 4.3.6. Click the drop down choice next to the SELECT BY button to choose one of the options.
