Here are some of the features and tips that could be useful. Some of these features only work with the device specific build, and not with Generic and BlackBerry.
- quick access buttons. from anywhere in the app, press 0 to go back to inbox. 9 to show first few lines of the message without actually opening it.
- customizable shortcuts. customize up to 10 shortcuts. e.g. #0 to tag the current message with "Important". #1 to trash the current message.
- powerful server side search. the same flexible powerful search is also available on J2ME client. saved search is especially useful on mobile clients without keyboard.
