If SELECT BY CURSOR is toggled ON, the user can select elements in the following four ways.

Select to pick an element by its location.

Select to pick elements on a surface.

Select to pick elements inside a window.

Select to pick elements inside a free hand region.

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.
