M-R   Replace all instances of first typed-in string with second
          typed-in string.  End each string with ESC.

=>  (6) REGIONS & THE KILL BUFFER

M-<spacebar> set MARK at current position
^X ^X  eXchange mark and cursor

A REGION will then be continuously-defined as the area between the mark and
the current cursor position.  The KILL BUFFER is the text which has been
most recently saved or deleted.
-----------------------------------------------------------------------
=>  (7) COPYING AND MOVING

^W  Delete (Wipe) region  M-W copy region to KILL buffer
^Y  Yankback save buffer at cursor
Generally, the procedure for copying or moving text is:
    1)  Mark a REGION using M-<spacebar> at beginning and cursor at end.
    2)  Delete it (with ^W) or copy it (with M-W) into the KILL buffer.
    3)  Move the cursor to the desired location and yank it back (with ^Y).
-----------------------------------------------------------------------

^X ^M   Delete mode in buffer           M-^M   Delete global mode
OVER  Replaces (overwrites) rather than inserts characters
WRAP  Turns on word wrap (automatic carriage return).
VIEW  Allows viewing file without insertion and deletion.
CMODE  Automatic indenting for C program entry
EXACT/MAGIC Changes how search and replace commands work (see next page)

                                   file size and character under cursor
M-^C  Count words/lines/chars in marked region
-----------------------------------------------------------------------
