#### 1.4.7 Region Commands

Vi operators like `d`, `c` etc. are usually used in combination with motion commands. It is now possible to use current region as the argument to these operators. (A region is a part of buffer delimited by point and mark.) The key `r` is used for this purpose. Thus `d r` will delete the current region. If `R` is used instead of `r` the region will first be enlarged so that it will become the smallest region containing the original region and consisting of whole lines. Thus `m . d R` will have the same effect as `d d`.
