Extrude Individual: You can create an extrude from multiple
elements like you were selecting each one individually. The
extrudes will go in a unique direction for each selected element.
Extrude to Cursor: The extrude will go to the mouse cursor
location. It will create irregular shapes depending on the cursor
position on the screen
Another way to call those different extrudes is with the ALT+E key that
brings the Extrude menu to the screen (Figure 3.9).

In some cases, you will also see the contextual menu that appears when
you create objects in the 3D Viewport. You can change values for the
offset (length) of your extrude (Figure 3.10).
