Because the subject of a message doesn't always describe the task that you need to do, you'll be glad to know that you can change the subject of a flagged message in the To-Do Bar. When you do this, the subject of the message in the Inbox is unchanged.
So, you may wonder: What's the difference between a flagged message and a task created by dragging to the Tasks button? The answer is that it's mostly a matter of style.
- If you like to delete messages after you've finished with them, you'll probably prefer to use Tasks to keep track of things you need to do. (When you drag a message to the Tasks button, you create a new item, so deleting the message doesn't affect the task.)
- If you like to keep your messages (either in your Inbox or in folders — which we'll talk about in a later lesson), you'll probably prefer to use follow-up flags because flagging is quick and easy.
