vip: Region Commands
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’.
