shortcut to change layer/add via while routing in Altium doesn' t work
I'm doing this way:
1.- draw a track until the pcb point of change,
2.- once there I click with left button (mouse) the track one time.
3.-Here, I press the change layer button.
4.- Here I was hopping to change the track layer.

You need to swap steps 2 and 3.
When you click the &quot;change layer&quot; button it will (IIRC) produce a via on the end of your track, which you can then move around where you want it before left-clicking to choose its final location.
