yes, this is especially important when you consider that editing config
files often requires making substantially the same change to many lines.
the generic example:
/oldtext
cwnewtext
:map , n.
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
a more concrete example. your network has been renumber and you need to
change all occurences of 192.168.1 with 192.168.200 in the following text.
IPADDR="192.168.1.2" # REPLACE with YOUR IP address!
NETMASK="255.255.255.0" # REPLACE with YOUR netmask!
NETWORK="192.168.1.0" # REPLACE with YOUR network address!
BROADCAST="192.168.1.255" # REPLACE with YOUR broadcast address, if you
GATEWAY="192.168.1.1" # REPLACE with YOUR gateway address!
1G # move to start of file
/192.168.1 # search for 192.168.1
5cw192.168.200<ESC> # change 5 'words' to 192.168.2
n # find next
. # repeat change
n # find next
. # repeat change
n # find next
. # repeat change
:x # save and exit
takes probably all of 5 seconds. to do the same in a modeless editor
like pico or joe would involved dozens of extra cursor movement, insert,
and delete commands (you can't just do a simple overstrike because
'.200' is longer than the '.1')
you could also do the same with search and replace (but there are many
similar types of edit jobs where S&R is not appropriate because it may
have unintended consequences...e.g. you want to change some but not all
occurences of a string).
Even where S&R is appropriate, it is much simpler to type:
:%s/192.168.1/192.168.200/g
than it is to type or mouse-click your way through one or two or more
dialog boxes (i.e. mode changes).
