Shortcut key to move a line of text up or down in Long Text fields

I use Long Text for subtasks. It is important for me to be able to easily and quickly change the priority of these subtasks by reordering them.

For example, if I had the list:

  • Task 1
  • Task 2
  • Task 3

If my cursor was blinking on “Task 2”, I want to be able to press something like “Cmd + ↑” and it would switch the order of Task 1 and Task 2, like so:

  • Task 2
  • Task 1
  • Task 3
