Examples:
---------
The following example performs a global search with replace. 
We want to search for "feo" and change it for "lindo": 
:g/feo/s//lindo/g


If you want to use special characters you need to use \ (backslash). 
For example: to replace all the $ with **:
:g/\$/s//**/g

:1,5de Delete from line 1 to 5.

:1,5co20 Copy from line 20 5 lines

:1,5mo20 Same as before but cutting those lines

:g/XXX/s//YYY/g Changes on the full text XXX with YYY.


:s/old/new      replace next occurence of old with new
:s/old/new/g    replace all occurences on the line
:x,ys/old/new/g replace all ocurrences from line x to y
:%s/old/new/g   replace all occurrences in file
:%s/old/new/gc  same as above, with confirmation
