Selection User Interface

Both selection by point and selection by area are supported directly using standard mouse bindings. Selection by point is accomplished by clicking the left mouse button, and selection by area is accomplished by drawing a selection rectangle with the left mouse button. The modes of selection are supported using modifier keys. The following table describes the standard selection mouse bindings.

Modifier	Left Mouse Click	Left Mouse Drag
None	Single-Select Point	Single-Select Box
`Shift`	Add-Select Point	Add-Select Box
`Ctrl`	Sub-Select Point	Sub-Select Box

Partial selection is controlled via function key F4. This key toggles partial selection on and off. Both partial point selection and partial area selection are affected. This key binding toggles the window environment variable partialSelect.
