There is no such Command


           Swap Point and Mark                             C- X  C-X

             Exchanges The previously  set  mark  with  the  current
             cursor.  Lets  you  see  just what area is marked. Also
             useful for switching back and forth between  two  areas
             of text.

           Overprint Mode                                    C- X  O

             Sets overprint mode, where typing new  characters  will
             replace  any  characters  already  on  the  screen, and
             rubouts will leave blank space. Recursively  calls  the
             EDMACS command loop.

	     To exit overprint mode, use C-X Q.
 
           Set Key                                           C- X  #

             This is one of EDMACS's  most  powerful  functions.  It
             alters  the  current state of the keymap. This lets you
             redefine commands from the keyboard, and allows you  to
             bind   commands  created  during  the  current  editing
             session to keys. It prompts you twice. The first prompt
	     asks  you  for  a  Q-reg name and routine  number.  The
	     second prompt wants to  know what key you want to  bind
	     the function to.

	     See the EDMACS manual for more details.  This is NOT  a
	     command to use casually.

           Enable TECO commands                              C- X  $

             EDMACS's ability to pass TECO commands directly to TECO
             via the "execute TECO" command will not work unless bit
             14  (value 16384) of Qk is set. This command provides a
             convenient way to turn this feature on.
 
           Quit EDMACS                                       C- X  Q

             Exit  the  command  loop.  This command really works by
             making Qg negative, which  you  should  never  allow  a
             macro  to  do  unless  it  is  your intent to leave the
             command loop.  This command is  also used to leave  the
 	     recursively called command loop used by "overprint mode.

           Page File                                       C- X  C-P

             Reads  in the next page of the input file after writing
             the buffer onto the output file. Behaves  exactly  like
             TECO's  P  command,  except does nothing if there is no
             output file open. (TECO complains bitterly about that).

		(sorry there is a bug when no file is open.... it'll
		 get fixed soon)

           Exit and save                                   C- X  C-Z

             Behaves just like TECO's EX command, except asks you to
             confirm before saving your file.
	     
	     If there is no open file to be saved AND the buffer is empty,
	     EDMACS will exit without asking for confirmation.

           Append Page                                     C- X  C-A

             Same as TECO's A command. Appends page from input  file
             to end of buffer.

           Yank Page                                       C- X  C-Y

             Same as TECO's Y command. Yanks page  from  input  file
             into  buffer.  Does  nothing  if the text buffer is not
             empty.

           Save Intermediate File                          C- X  C-W

             Allows  you  to  save the file you are editing, without
             losing your place. A marker is placed in the saved file
             to hold the place, and will be removed by a normal save
             from the same EDMACS session, or may be removed by TECO
             with the /FIND switch.

           Visit File                                      C- X  C-V

             The all purpose filing command. Visit file displays the
             following behaviour:
          1)  If no file is open goes straight to step 2 else offers
             to save the file. You may answer Yes or  No.  answering
             Yes  saves  the  file,  answering no causes all changes
             made to be discarded.
          2) Gives a name of a  file  to  edit.  Typing  a  carriage
             return  will  cause  EDMACS to edit that file. Typing a
             filename instead will cause EDMACS to edit or create  a
             file with the new name.

	     This command is also  useful as an aid to  transferring
	     text from  one file  to another.
