You can type messages easier and faster with one-hand wherever you are! What is Good about AEI Keyboard - Only One Push to input Vowel (letter). - Less than Two Push to input Alphabet. (any letter) - Input faster with Two Thumbs. ************************************************* *This Keyboard works only in this App. SPECIAL FEATURES: * Friendly alphabetical character array with 13 multi input keys with just 2 characters each in order to type faster and easier * Dedicated Keys equipped above the alphabet keys for typing inverted exclamation mark/question mark and Spanish major extended characters easier (eg. If you intend to type “ñ”, type “MN;” key twice for “n” and then type the dedicated key “~”.) * Ideal key size that reduces probability of typographic errors * Arrow keys to move caret right and left faster for easier text editing * Useful keyboard Settings (touch the “tools” icon): * Auto determination of character typed with multi-input key (eg.

Just hit “QRRR” key 3 times to input “rr”) * Auto capitalization on the 1st letter of each sentence * Useful buttons equipped: *“Borrar(Clear)” button to erase subject and/or body of the message immediately *“Ocultar(Hide)” button to hide the keyboard for better view of longer messages *“Mail” button to send the text to Mail application *“Other” key to call another keyboard with major extended characters (multi input keys) ----------------------------------------- Please check our website www.4us.jp Thank you!
