Moving, Duplicating and Deleting

The most common thing you'll do in your editor is move, duplicate and delete lines. Historically, we have done this with the use of copy/paste and the delete key when necessary. VS Code contains functionality that makes this process much more productive.
Here are a few more keyboard shortcuts to add to your repertoire.
Action
Keyboard Shortcut
Duplicate line
Opt/Alt + Shift + Down/Up Arrow
Move line
Opt/Alt + Down/Up Arrow
Delete Line
Cmd/Ctrl + Shift + K
Note that you don't need to select a line in VS Code to copy/cut it. Just put your cursor anywhere on the line and press Cmd/Ctrl + C or Cmd/Ctrl + X and the entire line will be cut or copied. This is the default behavior of the editor.
