I found MLCad tutorial, and it looks like not what I'm looking for. It effect only the view? I need to move the pin on further(later) step, not on the current
Buffer exchange it not a LDCad specific feature, it is a collection of special LDraw meta lines.
Which basically let you take a 'picture' of the current model which can then be used to restore that situation some time later (removing anything added since the picture was taken).
This can be used to place a pin at two different locations in between steps. Downside is you have to re-add all other parts of that step too.
It is discussed in some more detail here:
