I believe you mean obfusticated or scrambled text in which case you must paste in §k before the text and §r after. Try it in a book to see if it's what you mean.
The resolution would worsen.
If you edit a document then you read through the document and revise or correct the document. In word processing this can mean deleting text, formatting text, replacing words, inserting page breaks, inserting headers and footers or page numbers, changing fonts, etc
If you mean typing text in the middle of some existing text, then it is Insert mode as opposed to Overwrite mode. You can also copy or cut text and then paste it into the middle of some existing text, whether you are in Insert or Overwrite mode.
Click and highlight the text written then right click and it will give you options and press copy then go on to where ever you want it to be pasted and right click there and press paste (an option on the given list)
