A look at a directory opens a pane listing it, as acme's directory window: named dir/, its entries in acme's columns (bytewise, dotfiles kept, a directory's marked /), a look at an entry from there, Get or a look again reads it again, never dirty, Save refused; DirLook terminal keeps ls in a terminal
