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

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.

^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).
