In VIM editor how can some specific words be always highlighted?

Question

A few words such as TODO remain highlighted always in VIM.

Can I add some custom words to this list which I want to be highlighted always?

Answer 1

Todo is a syntax group, :h group-name to check detail.

If you want to make some words/text highlighted, you can either edit syntax file, or create your own hi-groups (:h highlight-groups) and add match.

For example:

You can do match todo /!Important!/ to let text !Important! to be highlighted in same way as TODO. Or:

hi! Important ctermbg=red guibg=red

this will create a hi-group called Important.

Then you add match:

:match Important /!Important!/

this will highlight text !Important! in the way you defined in the group.

You could also add those lines in your vimrc.
