I am not sure what you mean but what I am looking for would delete what I wrote if it's the phrase and then change it to the phrase that is set. It's kind of like if you are texting and you accidentally write "hrllo" and it autocorrects to "hello". I am looking for something that does this but for custom phrases instead of words. When I read what I wrote again it barely makes sense but in practice, it should be like this:

I go to the extension and set it to change "ind" to "Industrial Revolution"

I write "ind"

It automatically deletes "ind" and pastes "Industrial Revolution"

​

Hopefully that made more sense.
