edit.html: Duplicate selected column/row as in VSCode

[neoneye]

Problem

VSCode has Option+ArrowUp or Option+ArrowDown.

It duplicates the row and places the cursor either up or down depending on if ArrowUp or ArrowDown was used.

It's a keyboard shortcut I use several times a day.

It may be handy for duplicating columns with Option+ArrowLeft and Option+ArrowRight.

Solution

Try it out.
