主要是对于 move to 和 apply labels 的问题
下面有两段解释
================================
Look at "Inbox" just like another label.Archive = Remove from Inbox
Move to = Remove all current labels and apply the new one.
So, if the msg is currently in the Inbox, this action will remove it from from the inbox (=archive) and apply the label
Labels = Add a label to the message without changing the current labels.

It seems as though there are 3 modes when viewing Gmail messages:
1. Mailbox Mode:
- Invoked by: clicking a mailbox on the top left (e.g. Inbox, Starred, etc.).
- Interface: Blue
- URL: ends with
#inbox,#starred, etc. - Top left button:
- For Spam and Trash: Delete forever
- For all the rest: Archive
- Buttons available: Labels and:
- For Inbox, Spam and Trash: Move to
- For all the rest: Move to Inbox
- Dragging a message will: Move it
2. Label Mode:
- Invoked by: clicking a label on the left.
- Interface: Green
- URL: ends with
#label/[my-label]. - Top left button: Remove label "[my-label]".
- Buttons available: Move to and Labels.
- Dragging a message will: Move it
3. Search Mode:
- Invoked by: pressing the Search Mail button.
- Interface: Green
- URL: ends with
#search/[my-query]. - Top left button: Archive (There will also be the text Search results for:[my-query] to its left).
- Buttons available: Move to Inbox and Labels.
- Dragging a message will: Label it
Note that when you drag a message you can drop it on: Inbox, Starred, Spam, Trash, or one of your labels. If you are in search mode and drag a label onto a Mailbox, it will say Label, but it will actuallyMove the message.
You will notice that modes 1 and 2 behave almost exactly the same. When you click through to a message from a list, it will show the exact same buttons the list had.
Notice how Move to is only available when the concept of a folder is used. For example, the Inbox acts as a folder since a message can't be both in the Inbox and Spam (or Trash). Similarly, when you press on a label to go into Label Mode, it treats the label as if it were a folder (even though it may be tagged with multiple labels).
When you Move a message it will remove the label/folder you are currently viewing from the message and apply a new one. For example, say a message is marked as label-a, label-b, andlabel-c. Now you click on label-b on the left to enter Label Mode. Next, you move the message tolabel-d. What happens is label-b is removed and label-d is added. The other labels remain on the message. The message will now be labeled: label-a, label-c, label-d.
Similarly, if a message is in the Inbox and you Move it to the Trash, it will be removed from the Inboxand moved to the Trash.
When you use the Label feature, you simply choose which labels to add or remove. Nothing will be done automatically for you.
