PolyglotKeyboard is an application for polyglots, for people, who need to type different languages (nearly) simultaneously. It allows using simple keyboard shortcuts for writing desired special characters found in different alphabets. Currently it is developed with a special aim on African languages which use latin-based scripts. Its goal is to give users means of writing their native languages and as such to promote the preservation and growth of those languages and their cultures. This application for computers running Windows is a sister application of the AfricanKeyboard, which offers about the same functionality on Android mobile phones.
