Toolbar Button:
Use the Select menu > Select > Pointer/Window command or the button to immediately switch into "select mode." With the program in select mode, objects can be selected graphically in the active display window using the mouse cursor. Selected objects are indicated by dashed lines, and only objects that are present in the active window can be selected graphically.
The Select menu > Select > Pointer/Window command provides two methods for graphical selection:
By Pointer: Each mouse click on an object selects or deselects the object. Only one object at a time can be selected/deselected using this technique. If multiple objects lay one on top of the other, hold down the Shift key on your keyboard as you left click on the objects. When the Selection List form appears, click the name of the object you want to select in the list. After an object has been selected, clicking on it again using the “by pointer” technique will deselect it.
By Window: Draw a window around one or more objects to select them. If the mouse moves from left to right while dragging, only objects completely inside the window are selected. If the mouse moves from right to left while dragging, visible objects crossed by the rectangle will be selected. Window selections are additive; objects in the selection window that were previously selected will stay selected. Note the following about window selection:
As you drag your mouse a "rubberband window" appears. The rubberband window is a dashed rectangle that changes shape as you drag the mouse. One corner of the rubberband window is at the point where you first depressed the left mouse button. The diagonally opposite corner of the rubberband window is at the current mouse pointer position.
TIP: It is sometimes easier to select a single Joint by drawing a window around it.
