Mike, I notice you said Z E. Does that mean you don't use the toolbar OR have a lisp that simplifies it to ZE?
As for my list?
open
vlide
matchprop(ma)
ctc(changed object to current layer)
rotate
plj(join as polyline)
close
undo
ze or zd or zs (being zoom extents, dynamic or previous)
bedit or whatever block editor is
