You could use set on winkeyless 1800, with blanks for the NAV section. Del, end, pg dn only come in D row and there is no 1x Ctrl/Alt or 6x spacebar. Those keys may make it into the Generic/Alternates add on when I get that revised to replace the now redundant extra function row.
If you already ordered BASE, then you have an order in for the new full set.
