Silly vi tricks

  xp     This will delete the character under the cursor, and put it
afterwards.  In other words, it swaps the location of two characters.
 
  ddp    Similar to xp, but swapping lines.
 
  yyp    duplicate a line

  uu     Undo and redo last change.  (This will take you to the last
modification to the file without changing anything.)  You can also use
this to compare the changes to a line.  Make the changes to the line,
press U to undo the changes to the current line, and then press u to
toggle between the two versions.

  Put `and' around the current word
    map! `` <ctrl-v><esc>bi`<ctrl-v><esc>ea'

  Split a line at the cursor, and put a > at the beginning of the next
line.  (For quoting Usenet, etc).  If word wrapping is enabled, it

    map k k<ctrl-v><ctrl-g>
