Autocorrect looks at where each finger actually landed and at the words around it, so a slip onto a neighbouring key gets fixed while the words you meant stay as you typed them. FOUR LANGUAGES • English, Magyar (Hungarian), Español and العربية (Arabic), each with its own word list, autocorrect and suggestions. Direct access to accent alphabet. • Switch between the layouts you use with one key; turn the rest off TYPE YOUR WAY • Swipe typing: glide across the letters without lifting your finger • Suggestions and next-word predictions that learn the words and phrases you use • Press delete right after a correction to undo it, and ZKeys remembers the word • Your own shortcuts for each language, like "omw" → "On my way!" • Symbol hints on the keys, laid out like a real keyboard.
