A fun keyboard layout, each key being a nautical signal flag (has flags for 0-9 A-Z ĈĜĤĴŜŬ).

After install, go to Android settings, go to Language and input, then checkbox the Maritime Flag Keyboard (FlagKlavaro) as one of your active keyboards (set it as default if you're feeling brave, or later just use Choose input method from the Android notification bar).

Press & hold any key to access accented letters (supports for the the full European MES-2 accented letter range). Swipe left to reveal letters, swipe right to return to flag view, swipe up to lock upper case, swipe down for lower case again.

Based on the Google sample keyboard with thanks. Your privacy is respected, no internet connect required. Please do not rely on FlagKlavaro, always keep your default keyboards installed as well.
