Is there any addon that provides more functionalities to text input elements?

I want to be able to have text manipulation features like line moving, deleting, duplicating, or multiple text selection like in code editors. I suppose the extension will need to transform plain text input element into codemirror.

Is there such an add-on? I have looked at these but they are merely editors on browser:


hello @ganuongphap I am not aware of one off the top of my head, but will let you know if I come across one.

Thanks – Ed
