しつもんがあります How do I make a small tsu when typing in hiragana? For example: たのしかたです How do i put that small "tsu" in between "ka" and "ta"?

The small "tsu" is represented by double consonants in romaji. So that's how you would type it. For example, to enter たのしかったです, you would type "tanoshikattadesu". To enter いってらっしゃい, you would type "itterasshai". Just as you would spell it in romaji. Alternatively, you can type "x" before the hiragana you want to make it small. "tanoshikaxtsutadesu" "ixtsuteraxtsushai" This way, you can make some other hiragana small, not just small tsu, if there is any need for it.　(Not for all hiragana. Just some which are sometimes written small just for visual impact.) For example, はぁぁぁぁぁぁぁぁい！
