Tasks can be copied and pasted using the Windows clipboard.

Copying:

One or more tasks can be copied to the clipboard by selecting the task(s) from the Task List, and then using the Edit/Copy menu command.

Pasting:

Tasks can be pasted from the clipboard back into Active To-Do List.  The copy/paste feature allows you to quickly/easily duplicate tasks, or transfer any number of tasks from one to-do list to another.  When pasting tasks into Active To-Do List, all of the fields within a task are transferred.

Tasks may also be pasted as text into any application that accepts text, such as Notepad or Word.  When pasting a task in the text format there will be one task per line.  Each field in the task is tab delimited.  For text copying/pasting, the fields are placed in the same order as the columns in the Task List.  You can adjust which columns are displayed in the Task List, as well as their order.
