I note an anomaly in the behaviour of these two buttons when no files are selected.
@disablenosel
Copy COLLLIST
@disablenosel
Copy TO coll://Starred
@keydown:shift
Go coll://Starred NEWTAB=findexisting
Set VIEW=Thumbnails
Despite there being no files selected, the first button shows existing collections available as targets but shows New Collection as unavailable, with or without @disablenosel. The second button shows target collections as unavailable, with or without @disablenosel.
