[add-on idea] move line of text up and down

Add-on idea / request for a volunteer. It would be useful to have in Anki editor ability to move text up and down within the area of single field. It is possible for example in Linux text editor Kate or note taking app - Cherrytree. I do it with shortcut, for example Alt + arrow.
It is very handy when text is copied for example from dictionaries. It reduces the number of copy paste.
