This reminds me of the substitution mode of Tim Pope's amazing vim plugin [abolish](https://github.com/tpope/vim-abolish?tab=readme-ov-file#subs...)

Basically in vim to substitute text you'd usually do something with :substitute (or :s), like:

:%s/textToSubstitute/replacementText/g

...and have to add a pattern for each differently-cased version of the text.

With the :Subvert command (or :S) you can do all three at once, while maintaining the casing for each replacement. So this:

textToSubstitute

TextToSubstitute

texttosubstitute

:%S/textToSubstitute/replacementText/g

...results in:

replacementText

ReplacementText

replacementtext
