Thanks a lot for this interesting option

You think surely KCC is never happyCTRL+SHIFT+U (Uppercase)
CTRL+SHIFT+L (LowerCase)
CTRL+SHIFT+X (InvertCase)

I use that often for the names of variables like PB is no case sensitiveCTRL+SHIFT+F (FirstUppercase)
First Uppercase (example on forum, hello --> Hello --> hello)

Perhaps a futur release

So again thanks for the adding
Have a good day
