makePoint() to remove points from list

[Thomas Eschner]

Hello,

In a macro, I use
setKeyDown("shift"); makePoint(xact, yact); setKeyDown("none");
to add points to a multi-point selection. That works well.
When I try to remove a particular point by
if (selectionContains(xact, yact)) {
  setKeyDown("alt"); makePoint(xact, yact); setKeyDown("none");
}
this very point is not removed, but all others instead.
When I use that function directly from the multi-point selections menu, Alt-click does what it is supposed to do, i.e. removes the clicked-on point.

Any hints?

Kind regards,
Thomas

This bug is fixed in the 1.45g1 daily build. There is an example macro at
