- <count> S
- Change <count> lines.
- <count> c<move>
- Change from begin to endpoint of <count><move>.
- <count> cc

- <count> ~
- Switch lower and upper cases.
- <count> J
- Join <count> lines (default 2).
- Substitute (on lines x through y) the pattern
<pat> (default the last pattern) with <repl>. Useful
flags <f> are ‘g’ for ‘global’ (i.e., change every
non-overlapping occurrence of <pat>) and ‘c’ for
‘confirm’ (type ‘y’ to confirm a particular
substitution, else ‘n’ ). Instead of / any
punctuation CHAR unequal to <space> <tab> and <lf> can be used as
In Emacs, ‘\&’ stands for the last matched expression, so
s/[ab]+/\&\&/ will double the string matched by [ab].
Viper doesn't treat ‘&’ specially, unlike Vi: use ‘\&’ instead.
Viper does not parse search patterns and does not expand special symbols
found there (e.g., ‘~’ is not expanded to the result of the previous
Note: The newline character (inserted as C-qC-j)
can be used in <repl>.
- :[x,y]copy [z]

- :[x,y]t [z]
- Same as :copy.
- :[x,y]move [z]

- The above commands display certain buffer lines in a
temporary buffer. The first form above displays the buffer lines between
x and y. The second displays the lines of the buffer, which
match a given pattern. The third form displays the lines that do not
match the given pattern.
- Change upper-case characters in the region to lower-case.
- Change lower-case characters in the region to upper-case.
- Insert specified string at the beginning of each line in the region
- C-c M-p and C-c M-n
- In Insert and Replace states, these keys are bound to commands that peruse
the history of the text
previously inserted in other insert or replace commands. By repeatedly typing
C-c M-p or C-c M-n, you will cause Viper to
insert these previously used strings one by one.
When a new string is inserted, the previous one is deleted.
In Vi state, these keys are bound to functions that peruse the history of
destructive Vi commands.
