  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  control 
 
    (Or  "ctrl",  "^")  One  (or  a  pair)  of  {modifier 
  keys}  found  on  all  modern  {keyboards}.  If  the  control  key  is 
  held  down  while  pressing  and  releasing  certain  other  keys  then 
  a  "{control  character}"  is  generated,  e.g.  holding  control  and 
  hitting  A"  generates  control-A  ({ASCII}  code  1).  The  ASCII 
  code  for  the  control  character  is  generally  64  less  than  that 
  for  the  unmodified  character. 
 
  The  control  key  does  not  generate  any  character  on  its  own  but 
  most  modern  keyboards  and  {operating  systems}  allow  a  program 
  to  tell  whether  each  of  the  individual  keys  on  the  keyboard 
  (including  modifier  keys)  is  pressed  at  any  time. 
 
  Control  characters  mostly  have  some  kind  of  "non-printing" 
  effect  on  the  output  such  as  ringing  the  bell  (Control-G)  or 
  advancing  to  the  next  line  (Control-J).  Most  have  alternative 
  names  suggesting  these  functions  (Bell,  Line  Feed,  etc.). 
 
  See  {ASCII  character  table}.
