How to combine LAYOUT and NEW in Go command?

Hello. Leo's last button doesn't wotk for me. it do nothing, no new window, no anything.
as here
([GO NEW Layout=XXX Broken in 9.1.3.0?])

Go CURRENT Layout="XXX"
works, but it doesn't open lister in thumbnails mode.

Go  LAYOUT=Thumbnails CURRENT
Set VIEW=thumbnails
Show THUMBNAILSIZE 256 

last two commands doesn't work.
where's mistake?

P.S. sorry. that is right for now
Go LAYOUT=Thumbnails CURRENT VIEW=Thumbnails

P.P.S. a Leo's button works well. didn't see FROMSEL))) the embeded commads are what i need. thanx to lxp
