Just as you can move the task, it can be copied. Copying is a good way to make it easier to work with typified tasks that are often repeated and have the same process.
There are two ways to copy a task.
Copy via the three-dot menu
Go to a project detail or particular To-Do list. You can copy a task via the three-dot menu on the left from a task name. Click Copy task…

You have to select a project and To-Do list, where you want the copied task to be located. You can choose whether you want to copy comments and files attached. Confirm via Copy task.

Copy from the task detail
Go to the task detail and click Copy task… in the right menu.

Select a project and To-Do list where you want to place the copied task.
