On Wednesday Google released two small but important updates to the mobile version of Gmail. New to the service are keyboard shortcuts and address auto-completion; two time-saving features that desktop Gmail users have been enjoying for years.
The keyboard shortcuts (obviously) do not work on the iPhone. For now, Google is limiting them to Android phones with a physical keyboard. These are exactly the same as on the desktop version, so you don't need to re-learn anything.
The auto-completion, on the other hand, is available to everyone and is quite a time saver. It begins pulling up names from your contacts as soon as you type just one letter.
Auto-completion only works in the "to" field when typing a new e-mail though, and does not work on Gmail's search like you're able to do on the desktop variant by using the Gmail labs add-on. Hopefully that feature will trickle down to this mobile version,when trying to add search operators, or sort out messages from specific contacts.
One thing to note is that these new features are only available in the English version of Gmail mobile. Google has not said if, or when, they will make their way to other localizations of the service.
