Traditional T9

TT9 is an IME (Input Method Editor) for Android devices with hardware keypad. It supports multiple languages and predictive text typing. NOTE: TT9 is not usable on touchscreen-only devices.

All Source code and documentation are available on Github: https://github.com/sspanak/tt9.

Initial Setup

In order to use Traditional T9, you need to enable it as an Android keyboard. To do so:

• Go to Android Settings → System → Languages → Keyboards.
• Add Traditional T9 IME.

The actual menu names may vary depending on your Android version and phone.

Enabling Predictive Mode

With the default settings, it is only possible to type in 123 and ABC modes. In order to enable the Predictive mode, there are additional steps:

• Open the Configuration screen.
• Select the desired languages.
• Load the dictionaries.

If you don't do the above, there will be no suggestions when typing in Predictive mode.

Hotkeys

D-pad Up (↑):

Select previous word suggestion.

D-pad Down (↓):

Select next word suggestion.

0 key

• In 123 mode: type "0" or hold it to type "+".
• In ABC mode: type secondary punctuation or hold to type "0".
• In Predictive mode: type space or hold to type "0".

1 to 9 keys

• In 123 mode: type the respective number.
• In ABC and Predictive mode: type a letter/punctuation character or hold to type the respective number.

Text Mode Key (Hash/Pound/#):

• Short press: Cycle input modes (abc → ABC → Predictive → 123)
• Short press while typing: Change between UPPERCASE/lowercase.
• Long press: Select the next language.
• Number-only fields: Type a "#". Changing the mode is not possible in such fields.

Other Actions Key (Star/✱):

• Short press: Add a new word to the dictionary.
• Long press: Open the Configration screen.

Backspace Key (Back/↩):

• Just deletes text.

Note: "Back" key plays a somewhat special role in Android. This role needs to be preserved for your phone to remain usable. Have in mind the notes below:

• Short Press when there is no text: Go back to the previous screen (the system default action).
• Short Press when there is text: Some applications, most notably Firefox and Spotify, take full control of the "Back" key. This means, it may function as the application authors intended, instead of as backspace. In such cases, you could use the on-screen backspace instead. Unfortunately, nothing else could be done, because this is a restriction posed by Android.
• Long Press: Whatever the system default action is (i.e. show running applications list).

On-screen soft keys

All functionality is available using the keypad, but for convenience, on touchscreen phones or the ones with customizable function keys, you could also use the on-screen soft keys.

Left Soft Key:

Open the Configuration screen.

Right Soft Key:

Backspace.

Configuration Options

On the Configuration screen, you can choose your preferred languages, load a dictionary for Predictive mode or view this manual.

To access it:
