Some Keys on the iOS keyboard, when pressed and held for a second or so, revile Variants to the character being selected (see link) https://i.stack.imgur.com/4Hh4t.jpg
I'm curious to know if there is a certain way to add/remove to these variants - of course with Jailbreak. (It's impossible without J/B)
For Example, is there a way to add to the Key "l" when held to revile the string "lol"?
Thank you.
