   this string is *case-sensitive*.  If you set DOTFILE to "De",
   it will not hide files starting with "de", for example.
 
+  The current state of dotfile hiding is displayed in the window
+  title bar, immediately after the Filter information.
+
+  Note that even though you cannot see the files with this option
+  enabled, commands you write can still operate on these
+  files.  For example, if you define a command that does something
+  like:
+
+     c clean rm .*~ *~
+
+  This command will remove any backup (~) files, whether or not
+  you can see them in the interface.
