操作系统设计与实现源码

                                                                        


                     to describe)
      ESC ;          Insert a comment in a C program  (generates  /*  */
                     for you)
      ^X X           Exit the editor (same as ESC X and CTRL-X CTRL-X)

The major differences between ELLE with  the  mined  profile  and  mined
itself are:

   1. The definition of a 'word' is different for forward  and  backward
   word
   2. The mark is set with CTRL-^ instead of CTRL-@
   3. Use CTRL-G to abort a command instead of CTRL-\
   4. Use CTRL- to literally insert the next character, instead of ALT
   5. CTRL-E adjusts the window to put the cursor in the middle of it
   6. To get and insert a file, use ESC G instead of CTRL-G
   7. To go to line n, type ESC n CTRL-[ instead of CTRL-[ n
   8. You exit with CTRL-X CTRL-X and then answer the question with 'y'.
   9. There are many new commands, windows, larger files, etc.


Emacs Key Bindings

     If you do not  have  the  mined  profile  installed,  you  get  the
standard  Emacs  key  bindings.   These  are  listed below. Commands not
listed are not implemented.

   CURSOR MOVEMENT
      CTRL-F         Forward one character.
      CTRL-B         Backward one character.
      CTRL-H         Same as CTRL-B: move backward one character.
      ESC F          Forward one word.
      ESC B          Backward one word.
      CTRL-A         Beginning of current line.
      CTRL-E         End of current line.
      CTRL-N         Next line (goes to the next line).
      CTRL-P         Previous line (goes to the previous line).
      CTRL-V         Beginning of next screenful.
      ESC V          Beginning of previous screenful.
      ESC ]          Forward Paragraph.
      ESC [          Backward Paragraph.
      ESC <          Beginning of whole buffer.
      ESC >          End of whole buffer.

   DELETING
      CTRL-D         Deletes forward one character (the one  the  cursor
                     is under).
      DELETE         Deletes backward one character (the one to left  of
                     cursor).
      ESC D          Kills forward one word.
      ESC DEL        Kills backward one word.


                                                                        



                                                                        


      CTRL-K         Kills the rest of the line (to  the  right  of  the
                     cursor).
      ESC \          Deletes spaces around the cursor.
      ^X CTRL-O      Deletes blank lines around the cursor.

   CASE CHANGE
      ESC C          Capitalizes word : first letter becomes  uppercase;

      CTRL-S         Incremental Search forward; prompts 'I-search:'
      CTRL-R         Reverse Incremental Search; prompts 'R-search:'

                     During  an  incremental   search,   the   following
                     characters have special effects:

                     'normal'    - Begin searching immediately.
                     ^G          - Cancel I-search, return to start.
                     DEL         - Erase  last  char,  return  to   last
                                   match.
                     ^S, ^R      - Repeat search (or change direction).
                     ESC or CR   - Exit I-search at current point.

                     para.
      CTRL-W         Wipe-out -- kills a 'region':
      ESC W          Copy region. Like CTRL-W then CTRL-Y  but  modifies
                     buffer
      CTRL-Y         Yanks-back  (un-kills)  whatever  you   have   most
                     recently killed.
      ESC Y          Yanks-back (un-kills) the next most recently killed
                     text.

ELLE profile

     It is possible to create your own user profile.  The  mechanism  is
different  from  Emacs,  since ELLE does not have Mock Lisp.  Proceed as
follows.


   Modify .ellepro.e to suit your taste.

   Install .ellepro.e in your home directory.

   Type:

           ellec -Profile


   Check to see if .ellepro.b1 has been created.  If it has, you  are
   ready to go.
