Figure 3.24 - Merge results

If you want to use a dedicated shortcut for the Merge, you can also

press the M key with vertices selected. That will call a small menu with

Merge options only.

Tip: For the example in Figure 3.24, you can repeat the Merge to

connect the other vertices.

3.6.1 Fixing extrudes with the Merge

One of the uses for the Merge option in Blender is to fix problems

created by the extrude, where you might forget to undo a canceled

extrude during the transformation stage.

The problem appears when you press the E key to extrude and press

the ESC key before finishing the extrude. That cancels the

transformation, but the extrude's new elements will still exist in your

scene.
