noglob is a keyword (a "precommand modifier", specifically) that  
disables wildcard filename globbing:

   % cd /tmp
   % touch 'a*'
   % touch 'ab'
   % ls a*
   a*              ab
   % noglob ls a*

This trivial case isn't too useful, but consider wanting to copy  
all .jpg files from your home directory on another machine to the  
local machine via scp or rsync:

   noglob scp kline at machine:*.jpg .

It's also amazingly handy in conjunction with the "find" command:

   noglob find /usr/obj -name *.a much so that I do:

   alias find='noglob find' my ZSH environment.
