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’.
