Example: in your IDE you had a snake case variable: some_var, you want to convert to camel case someVar, you can go to the "_v" location, delete it using two deletes and add "V", that would maximize the reuse of written text. other ways - mouse double click on the var and write the whole name again, replace it using "replace" , use IDE functionality to convert snake to camel etc'...
another example is a sentence or a line where you need to switch two words position, would selecting the shortest word, deleting it using delete key and rewriting it in place or mark the word, cut, paste in place
many more examples out there
