(similar as Gustavo said, but additionally: )
For any previously search, you can do simply:
:%s///gn
A pattern is not needed, because it is already in the search-register (@/
).
"%" - do s/
in the whole file
"g" - search global (with multiple hits in one line)
"n" - prevents any replacement of s/
-- nothing is deleted! nothing must be undone!
(see: :help s_flag
for more informations)
(This way, it works perfectly with "Search for visually selected text", as described in vim-wikia tip171)
