unfortunately, it looks like "Global alternate" is hidden
in the UI with no
way to enable it (the code is there, but the column is always hidden). (In
KDE 3, there was just "Primary" or "Alternate" for both global and
application shortcuts, applications shortcuts had no "Global" version. So
this looks like a regression to me.)
