No new emoji's found on my update yet. Wanting the taco n middle finger. When they coming???
If you use them often enough, they'll eventually end up in the "FREQUENTLY USED" section of your emoji keyboard. It's easy enough to find and use them from there. But if you ever want to use them without even having to switch over to your emoji keyboard, tapping on the emoji, and then switching back to the English keyboard (or whichever your main language on your iPhone is), then you should definitely think about configuring these emojis as text replacements.
To do that, go to Settings > General > Keyboard > Text Replacement and add a new Text Replacement. A Text Replacement consists of two parts: a "Shortcut" and a "Phrase". When set up correctly, every time you type the "Shortcut", regardless of which app you happen to be typing in, the shortcut will automatically be expanded into the "Phrase".
For my purposes, I chose ":MID" to be replaced by the middle finger emoji, and I chose ":TAC" to be replaced by the taco emoji. Below is a screenshot of how it'll look once it's correctly set up. I added red arrows pointing to the text replacements in question.
You do not have to use my shortcut; you can choose any shortcut you like. For example, you might like "%MID" for your middle finger emoji and "%TACO" for your taco emoji. The choice is completely up to you. The important thing is to choose a shortcut that you're not likely to need to type for any other purpose! So, for example, if you often Tweet to your Twitter followers that you are eating a taco and follow it with #taco, then don't make #taco your shortcut for the taco emoji!
