You can copy and paste text on an iPhone or iPad just like you can on a computer. However, instead of a mouse or trackpad to select text and keyboard commands to copy and paste, you need to use touchscreen gestures to select and special on-screen commands to copy and paste. It takes some practice to be able to copy and paste as easily as you can on a computer.
Gary, I do not have the same keyboard config as you show in this video. My Keyboard selections are English/Enmoji, I have 'offered text words_would that be called predictive?' but not the other options. I'm on 11.4.1 iOS, its not a deal breaker for me, I copy past the hard way>although the bubble will come in handy now. I did not know about the mag bubble, cool, thanks.
joe: The keyboard varies depending on the app. And, of course, which version of iOS you have.
Gary, were you using NOTES ? (as I am )
I am on iPhone 7Plus, iOS 11.4.1.
I assume I have the up to day as of this moment NOTES. Courious!!
Joseph: I'm showing this on the iPad. So there's more space and thus different elements up there.
