How do I highlight multiple words in vim?

Solution 1:

I found the script.

You can download the script at here.
http://www.vim.org/scripts/script.php?script_id=2666

Just \m on the word you want to highlight.
You could select visual block then \m
And you could add more colors.

Solution 2:

If you are fine with multiple words being highlighted in the same color, simply go to search mode (type / in normal mode) and search words that are separated by \|

/word_1\|word_2\|word_3

You can use n and N to navigate as usual.
