#One of the first things I did when I started using Unix was to write 
#some simple vi macro commands which perform operations on blocks
#of lines.  This sort of thing (e.g. block copy, delete, or shift)
#is one of the most frequent things I do when editing, and I found it
#awkward to specify in unadorned vi.  By including some 'map' commands
#in my ~/.exrc , I created some two-character commands which greatly
#facilitate block operations.
#
map @@ mt
map @D $d'tmbkmt`b
map @Y mb$y't`b
map @C mxjmb`x$c't
map @> mb>'t`b3l
map @< mb<'t`b3h
map @: mb:'t,'b
map @d d`tmbhmt`b
map @y mby`t`b
map @c mbc`t
map @T `t
map @B `b
#
#This will create the following two-character commands:
#
#@@ - the current cursor position is marked as the 'top' of the block
#    you want to operate on.  After this is done, move the
#    cursor to the 'bottom' of the block and give one of the
#    following commands:
#
#@D - delete all lines of the block
#@Y - yank all lines of the block
#@C - delete all lines of the block and enter input mode
#@> - shift the entire block right by <shiftwidth> characters
#@< - shift the entire block left by <shiftwidth> characters
#  (note that the value of <shiftwidth> - 3 in my case - has to be
#      coded directly into the definitions for @> and @< )
#@: - enter ex command input mode after defining the block for an ex
#   command.  For example, '@:w foobar<return>' will write the block of
#   lines into a file named 'foobar'.
#@d - like @D, but operates on blocks of characters, not blocks of entire lines.
#@y - like @Y, but operates on blocks of characters, not blocks of entire lines.
#@c - like @C, but operates on blocks of characters, not blocks of entire lines.
#@T - return cursor to 'top' of block, defined by last @@ command.
#@B - return cursor to 'bottom' of block, defined by last @* command
#    (@* = @D, @Y, etc.)
