I'm on my iPhone a lot during the day, and when I want to get on FeralHeart, it's a bit of a hassle for me to format my post every time I'd like to say something. I do realize that copying and pasting is an option, but you need to copy more than one thing sometimes, so I found a better way.
Go to Settings >> General >> Keyboard >> Text Replacement, and click the plus sign on the top right corner.
Now, you should see an area with "phrase". Enter here what you'd like to say for short. { Ex: [ color=teal ] }
Under that, where you see "shortcut", enter a two or three letter shortcut for that. { Ex: te }
Whenever you write "te" and press enter..."[ color=teal ]" will pop up!
Of course, you can use this trick for anything, including having a short message at the end of texts, etc.
I hope this helped someone out!
