I found an interesting little thing: I right-click on a file in the list view and get the context menu. Then I move the mouse up and down the context menu. As I do this various bit of text appears on the status bar, telling me what the entry does. When the cursor gets to the separator above and below the “Send To” entry, the text “Mark this folder” appears on the status bar
