Instead of typing normally, you can also trace ("swipe") words with your finger. Just touch the first letter of the word and then drag successively through each letter until the end, then lift. The word Typefinity thinks you swiped will be inserted; if it's wrong, just select one of the other suggestions, or tap backspace if none of them are right. If Typefinity is having trouble recognizing the word, try sliding your finger more slowly over letters in the word than over the intervening letters.
If you would like a shorter keyboard when in landscape mode so you can see more of the screen, long-press the keyboard-away button to toggle the keyboard height. This setting is remembered between sessions, but does not apply in portrait mode or on the full-size iPad Pro. (The keyboard is already in "short" mode on that platform.)
Language Quick Switch
If you often use two different languages, you can switch between them quickly in Typefinity. Just hold down the Globe key and drag your finger up to the first button, which will have the initial letters of the two most recent language settings with an arrow between them. Releasing your finger will change to the most-recently used other language setting. You can repeat this process to toggle back and forth.
You can enter emoji with Typefinity in two ways. First, you can type them "ASCII art" style using punctuation symbols. For example if you enter :) or :-) Typefinity will show 🙂 on the suggestions bar. Select it to replace the ASCII version with the pictograph. The second way to enter emoji is to first enter a '/' or ':', then start typing a word for the emoji you want, for example "smile" or "grin". Typefinity will show emoji associated with this word on the suggestions bar.
