set movemode= { on | off}

When this option is set to on, it enables a mode used to move or copy a highlighted selection using only the keyboard. When enabled, the insertion cursor is changed to the drag and drop insertion cursor and it can be moved away from the highlighted selection using normal cursor keys to the new cursor position. This mode remains in effect until either the Enter key is pressed (which accepts the move or copy) or Escape (which cancels it). The default is off.

By default, F2 enables move mode and Shift+F2 enables copy mode.
