+While reading filenames in the minibuffer, @value{tramp} must decide
+whether it completes possible incomplete filenames, or not.  Imagine
+there is the following situation: You have typed @kbd{C-x C-f
+@value{prefix}ssh@value{postfixhop} @key{TAB}}.  @value{tramp} cannot
+know, whether @option{ssh} is a method or a host name.  It checks
+therefore the last input character you have typed.  If this is
+@key{TAB}, @key{SPACE} or @kbd{?}, @value{tramp} assumes that you are
+still in filename completion, and it does not connect to the possible
+remote host @option{ssh}.
+
+@vindex tramp-completion-mode
+External packages, which use other characters for completing filenames
+in the minibuffer, must signal this to @value{tramp}.  For this case,
+the variable @code{tramp-completion-mode} can be bound temporarily to
+a non-nil value.
