You just hit whatever key you want (`/' in this case) and that will
stop menucompletion. The `/' is this example is a bit magic (with the
AUTO_REMOVE_SLASH option set): if the completion code automatically
inserted the trailing `/' (as it normally does) and you hit `/' this
doesn't seem to change the command line. But what really happens is
that `/' is one of the characters that automatically remove the
inserted slash and then self-insert inserts it again.

The zle widgets for word movement/killing/whatever should all use the
$WORDCHARS special parameter. That gives the characters that are
normally considered to be part of a word (sans the alphanumeric ones
which are always considered to be part of words) -- and normally it
contains the slash. So you can just remove all characters from
$WORDCHARS where you want the cursor to be moved to or where you want
the word killing function to kill to.
