delete a batch of conversations, you can tap Undo in the green bar (that appears
briefly after the action) at the top of the Inbox screen to return the messages to the
Inbox or appropriate label. You can also use Undo after muting, archiving, and
reporting spam. If you never work with batches of messages, you can hide the check
boxes to leave more room for the subjects of conversations. (See Changing Gmail
Settings on page 151).
Labeling a Conversation
As mentioned previously, conversations are organized by labels. Gmail has several
default labels, but you can also add your own through Gmail on the Web.
To label a conversation or change a conversation's labels:
1. When viewing a conversation press
2. In the dialog box that opens, check the labels you want to assign to the
conversation and tap OK.
