Paste text when option not offered by the app?

Is there a way to paste message if an app doesn't offer the paste option when you hold down in the text area? (Specifically Clash of Clans.) Alternate keyboard for storing text or something like that? Or with iOS 8, a keyboard with a paste button?

With new keyboards, one option to accomplish this turned out the be Paste It! It's a keyboard app that lets you type into the main app, and then find any one of a number of messages to paste later. Nice!

I think there are other keyboards out there providing similar functionality, but this was the first free option I found.

Use shortcuts --- settings/keyboard
