Swap words in strings by hot keys

[Graf54]

Hello. I know that the functionality is similar already, but I would like the following
I want to set the cursor on one word and use the hot keys to change its place with other words.

was: "First! second? three_four. fiveSexSeven"

Set sursor on five and clicked 4 times ctrl+shift+alt+←

It became: "five! second? three_four. FirstSexSeven"

may also need to change the first letter
